ABSTRAK
Respon imun makrofag merupakan proses alamiah yang terjadi di dalam tubuh sebagai adaptasi terhadap benda asing/antigen. Makrofag merupakan komponen penting pada respon imun bawaan maupun adaptif, karena berperan pada proses fagositosis serta sebagai antigen presenting cell APC . Pada proses fagositosis makrofag memerlukan O2 dan energi yang tinggi. Penelitian ini bertujuan membuktikan bahwa pada makrofag peritoneum yang diimunisasi terjadi hipoksia relatif dan peningkatan biogenesis mitokondria dalam usaha meningkatkan keperluan energi. Untuk membuktikan terjadi hipoksia diukur ekspresi mRNA dan protein HIF-1? serta HIF-2? yang merupakan protein yang berperan pada respons terhadap hipoksia. Juga diukur ekspresi mRNA dan protein sitoglobin yang merupakan protein pengikat O2. Untuk menilai biogenesis mitokondria diukur kadar protein PGC-1?. 24 ekor mencit BALB/c dibagi menjadi 3 kelompok perlakuan imunisasi dan 1 kelompok kontrol. Hasil penelitian menunjukkan bahwa terjadi hipoksia yang ditunjukkan oleh peningkatan bermakna kadar protein HIF-1? p=0.000, ANOVA dan HIF-2? p=0.035, ANOVA mulai dari 24 jam dan terus meningkat sampai 72 jam setelah imunisasi. Ekspresi protein sitoglobin meningkat mulai 24 jam sampai 72 jam setelah imunisasi p=0.01, ANOVA , sedangkan ekspresi protein PGC-1? meningkat bermakna pada 72 jam setelah imunisasi p=0.047, Kruskal-Wallis . Disimpulkan pada makrofag peritoneum mencit yang diimunisasi terjadi hipoksia dan biogenesis mitokondria. Kata kunci: Sitoglobin; HIF-1?; HIF-2?; Makrofag; PGC-1?
ABSTRACT
Macrophages rsquo s immune response is natural process that occurs in the body. Macrophages is important in innate and adaptive immunity, due to their role in phagocytosis as well as antigen presenting cell APC . Phagocytosis itself requires O2 and high energy. This study aims to investigate that immunized peritoneal macrophages were in relative hypoxia condition and its mitochondrial biogenesis increased in efforts to provide energy. To confirm hypoxia were calculated by mRNA and protein expression of HIF 1 and HIF 2 . mRNA and protein Cygb expression were also measured as the protein considered binds O2. To assess mitochondrial biogenesis, PGC 1 protein level were measured. 24 male BALB c mice were used and divided into three immunized treatment groups and one control group. The results showed that hypoxia occur, affirm by a significant increase in protein levels of HIF 1 p 0.000, ANOVA and HIF 2 p 0.035, ANOVA ranging from 24 hours and continued to increase until 72 hours. Cygb protein expression also increased from 24 hours to 72 hours p 0.01, ANOVA , whereas the expression of PGC 1 alpha protein increased significantly at 72 hours p 0.047, Kruskal Wallis .

Latar belakang: Periodontitis merupakan penyakit inflamasi kronis dan dikenal dalam berbagai klasifikasi, yaitu periodontitis kronis, periodontitis agresif, necrotizing periodontitis, dan periodontitis sebagai manifestasi penyakit sistemik. Periodontitis agresif ditandai dengan meningkatnya proporsi bakteri Aggregatibacter actinomycetemcomitans, namun belum terdapat studi yang secara spesifik membuktikan interaksi langsung antara sel bone marrow-derived macrophages (BMM) sebagai prekursor sel osteoklas dengan bakteri Aggregatibacter actinomycetemcomitans. Tujuan: Menganalisis interaksi langsung antara sel BMM dengan bakteri Aggregatibacter actinomycetemcomitans. Metode: Sel bone marrow dikultur selama 48 jam untuk menjadi sel BMM dan kemudian diinfeksikan oleh bakteri Aggregatibacter actinomycetemcomitans selama 5, 15, dan 30 menit pada kondisi aerob dan anaerob. Data jumlah koloni bakteri Aggregatibacter actinomycetemcomitans didapatkan melalui uji total plate count (TPC). Analisis kuantitatif melalui uji statistik. Hasil: Terjadi peningkatan bermakna jumlah koloni bakteri pada kelompok bakteri Aggregatibacter actinomycetemcomitans yang berinteraksi dengan sel BMM, dibanding tanpa sel BMM pada kelompok paparan aerob 5 dan 15 menit. Tidak terdapat perbedaan pada jumlah koloni bakteri Aggregatibacter actinomycetemcomitans yang diinfeksi pada kondisi aerob atau anaerob. Tidak ada perbedaan bermakna pada jumlah koloni bakteri Aggregatibacter actinomycetemcomitans yang diinfeksi selama 5 menit, 15 menit, dan 30 menit. Kesimpulan: Interaksi langsung antara sel BMM dengan bakteri Aggregatibacter actinomycetemcomitans memengaruhi proliferasi bakteri Aggregatibacter actinomycetemcomitans. Proliferasi bakteri Aggregatibacter actinomycetemcomitans dipengaruhi oleh kondisi aerobik dan anaerobik, namun tidak dipengaruhi lama waktu infeksi. ......Background: Periodontitis is a chronic inflammatory disease and classified as chronic periodontitis, aggressive periodontitis, necrotizing periodontitis, and periodontitis as a manifestation of systemic disease. Aggressive periodontitis is characterized by an increased in Aggregatibacter actinomycetemcomitans proportion. There has not been any studies that have shown the direct interactions between bone marrow derivedmacrophages cells, as osteoclast precursor cells, with Aggregatibacter actinomycetemcomitans. Purpose: To analyse direct interactions between bone marrowderived macrophages (BMM) cells and Aggregatibacter actinomycetemcomitans. Methods: Bone marrow cells from C57BL/6 mice were cultured for 48 hours in order to differentiate into BMM cells. BMM cells were then infected with Aggregatibacter actinomycetemcomitans for 5 minutes, 15 minutes, and 30 minutes in an aerobic and anaerobic environment. Total plate count of Aggregatibacter actinomycetemcomitans were analysed as a quantitative data using statistical analysis Results: Statistically, significant difference between Aggregatibacter actinomycetemcomitans-infected BMM and control group were observed on 5 minutes and 15 minutes aerobic groups. There were no statistically difference in Aggregatibacter actinomycetemcomitans colony count number between cultures in aerobic or anaerobic environment. No statistically significant difference were found in Aggregatibacter actinomycetemcomitans colony count number between 5, 15, and 30 minutes infection time. Conclusions: Direct interactions between BMM cells and Aggregatibacter actinomycetemcomitans affect Aggregatibacter actinomycetemcomitans proliferation. Bacterial proliferation is affected by aerobic or anaerobic environments, but not infection time

Latar Belakang: Penggunaan PRP autologus banyak dimanfaatkan untuk mempercepat proses penyembuhan berbagai macam luka, namun belum ada kriteria yang mengatur penggunaan tersebut. Penelitian yang menjelaskan bagaimana pengaruh penggunaan PRP terhadap proses tersebut juga masih sangat terbatas. Penelitian ini bertujuan untuk mengalisa pengaruh PRP terhadap produksi mediator pro dan anti-inflamasi dari kultur makrofag.Metode: Penelitian eksperimental ini menggunakan sampel darah perifer dari subyek sehat yang diambil sebanyak 2x dengan interval waktu 1 minggu. Pada pengambilan darah pertama, dilakukan isolasi sel monosit kemudian dikultur selama 1 minggu menjadi sel makrofag. Pada hari ke-7 dilakukan pengambilan darah kedua untuk dilakukan isolasi PRP dan serum, kemudian dilakukan 5 kelompok perlakuan berbeda terhadap masing-masing subyek. Kelompok I, makrofag ditambah serum. Kelompok II, makrofag ditambah serum dan LPS. Kelompok III, makrofag ditambah serum, LPS, dan PRP. Kelompok IV, makrofag ditambah LPS dan PRP. Kelompok V, makrofag ditambah PRP. Pada hari ke-10 dan ke-14, kadar sitokin TNF-a dan IL-10 yang dihasilkan dari kultur makrofag diukur dengan menggunakan teknik ELISA.Hasil: Terjadi penurunan bermakna kadar TNF-a hari ke-14 dibandingkan hari ke-10 pada kelompok II p=0.001 , kelompok III p=0.011 , dan kelompok IV p=0.000 . Kemampuan sel makrofag untuk memproduksi TNF-a menurun pada hari ke-14 dibanding hari ke-10. Terjadi peningkatan bermakna kadar IL-10 hari ke-14 dibandingkan hari ke-10 pada kelompok I p=0.05 , kelompok II p=0.018 , kelompok III p=0.017 , kelompok IV p=0.030 , dan kelompok V p=0.030 . Kemampuan sel makrofag untuk memproduksi IL-10 meningkat pada hari ke-14 dibanding hari ke-10, namun tidak ada perbedaan bermakna antar tiap kelompok.Kesimpulan: Secara umum, kadar TNF-a menurun pada hari ke-14 dibandingkan hari ke-10 sedangkan kadar IL-10 meningkat pada hari ke-14 dibandingkan hari ke-10. Pemberian PRP dapat meningkatkan produksi kadar TNF-a pada awal aktivasi makrofag dan menurunkan produksi TNF-a pada akhir aktivasi makrofag. Pemberian PRP tidak mempengaruhi produksi IL-10 pada awal aktivasi makrofag dan meningkatkan produksi IL-10 pada akhir aktivasi makrofag.
ABSTRACT
Background Autologous PRP has been used widely to accelerate wound healing, but many are case reports lacking controls. Research explains how the effect of the use of PRP to the process is still very limited. This study was aimed to analyze the effect of PRP on the production pro and anti inflammatory mediators from macrophage culture.Methods This experimental research was prepared from peripheral blood samples collected 2 times from healthy subjects, within an interval of 1 week. In the first blood collection, monocytes were isolated then cultured for 1 week into macrophage Human monocyte derived macrophages . On day 7, the second blood collection was done to isolate PRP and serum, then 5 different treatments were treated to each subject. Group I, macrophage plus serum. Group II, macrophage plus serum and LPS. Group III, macrophage plus serum, LPS, and PRP. Group IV, macrophage plus LPS and PRP. Group V, macrophage plus PRP. On day 10 and day 14, cytokine TNF a and IL 10 that produced by macrophage culture were measured using ELISA technique.Results There was significant decrease of TNF a concentration on day 14 compared to day 10, especially in Group II p 0.001 , Group III p 0.011 , and group IV p 0.000 . Macrophage rsquo s ability to produce TNF a was decrease on day 14 compared to day 10. There was significant increase of IL 10 concentration on day 14 compared to day 10, in Group I p 0.05 , Group II p 0.018 , Group III p 0.017 , Group IV p 0.030 , and Group V p 0.030 . Macrophage rsquo s ability to produce IL 10 was increase on day 14 compared to day 10, but there was no significant difference between each group.Conclusions In general, TNF a concentration decrease on day 14 compare to day 10 but IL 10 concentration increase on day 14 compare to day 10. PRP supplement can increase the production of TNF a in the first phase of macrophage activation and reduce the production of TNF a in the late phase of macrophage activation. PRP supplement doesn rsquo t influence the production of IL 10 in the first phase of macrophage activation but can induce the increasing of IL 10 production in late phase of macrophage activation.

Abstrak :
Diabetes melitus banyak dikaitkan dengan risiko tinggi aterosklerosis dan komplikasinya. Makrofag merupakan kunci dalam semua tahap aterosklerosis dan sudah diketahui berperan penting dalam patomekanisme penyakit metabolik dan kardiovaskuler. Makrofag menginternalisasi LDL teroksidasi melalui scavenger receptor seperti CD36. Makrofag juga mempunyai sistem transpor aktif seperti ABCA1 untuk eliminasi kolesterol dari makrofag ke akseptor ekstraseluler. Keterlibatan protein CD36 dan ABCA1 dalam mekanisme masuk dan keluarnya kolesterol pada makrofag diduga berhubungan dengan risiko pembentukan sel busa  sehingga diperlukan penelitian pola ekspresi CD36 dan ABCA1 serta ekspresi sitokin pro-inflamasi  IL-1b dan anti inflamasi IL-10 makrofag pada subyek non T2DM dan T2DM. Pengamatan dilakukan pada 11 subyek non T2DM dan 13 subyek T2DM. Disain penelitian menggunakan studi obervasional dan intervensi invitro. Monosit distimulasi menjadi makrofag menggunakan M-CSF. Tahap selanjutnya, makrofag dibagi dalam tiga perlakuan yaitu tanpa stimulasi, stimulasi LPS dan stimulasi ox-LDL. Ekspresi makrofag CD36 dan ABCA1 diukur  secara flowcytometri menggunakan alat BD FACSCanto II Flow Cytometer sedangkan ekspresi IL-1b dan IL-10 makrofag diukur  dengan multiplex immunoassay pada alat LuminexTM 200. Pada penelitian ini ditemukan adanya hubungan negatif rasio Trigliserida/HDL dengan ekspresi makrofag CD36-ABCA1+. Makrofag yang distimulasi ox-LDL menunjukkan perbedaan ekspresi CD36+ABCA1- pada subyek non T2DM dan T2DM yang tidak signifikan (p=0,12) sedangkan  ekspresi CD36-ABCA1+ menunjukkan perbedaan yang signifikan (p=0,04). Subyek non T2DM menunjukkan ekspresi CD36-ABCA1+ dominan tinggi (72.7%) sedangkan pada subyek T2DM dominan ekspresi rendah (59.2%). Makrofag yang distimulasi LPS dan ox-LDL menunjukkan perbedaan rasio IL-1b/IL-10  pada subyek non T2DM dan T2DM (p=0.05; p=0.02). Subyek T2DM menunjukkan rasio IL-1b/IL-10 lebih tinggi dibandingkan non T2DM. Analisa hubungan rasio IL-1b/IL-10 dengan ekspresi makrofag CD36-ABCA1+ menunjukkan kecenderungan subyek dengan rasio IL-1b/IL-10 tinggi mempunyai ekspresi makrofag CD36-ABCA1+ rendah. Analisis juga menunjukkan 62% subyek T2DM menunjukkan eskpresi makrofag CD36- & ABCA1+ rendah disertai rasio IL-1b/IL-10 tinggi  dan hsCRP diatas nilai median sedangkan subyek non T2DM 91% menunjukkan ekspresi CD36-ABCA1+ tinggi dengan rasio IL-1b/IL-10 rendah dan hsCRP rendah.  Pada penelitian ini ditemukan adanya hubungan ekspresi makrofag CD36-ABCA1+ dan  rasio IL-1b/IL-10 terhadap hs-CRP yang merupakan penanda risiko penyakit kardiovaskuler. ......Diabetes mellitus is associated with a high risk of atherosclerosis and its complications. Macrophages are key in all stages of atherosclerosis and are known to play an important role in the pathomechanism of metabolic and cardiovascular disease. Macrophages internalize oxidized LDL via scavenger receptors such as CD36. Macrophages also have active transport systems such as ABCA1 for elimination of cholesterol from macrophages to extracellular acceptors. The involvement of CD36 and ABCA1 proteins in the mechanism of entry and exit of cholesterol in macrophages is thought to be associated with the risk of foam cell formation, so it is necessary to study the expression patterns of CD36 and ABCA1 as well as the expression of the pro-inflammatory cytokine IL-1b and anti-inflammatory IL-10 in macrophages in non-T2DM subjects and T2DM. Observations were made on 11 non-T2DM subjects and 13 T2DM subjects. The research design used observational studies and in vitro interventions. Monocytes were stimulated to become macrophages using M-CSF. In the next stage, macrophages were divided into three treatments: no stimulation, LPS stimulation and ox-LDL stimulation. The expression of CD36 and ABCA1 macrophages was measured by flowcytometry using the BD FACSCanto II Flow Cytometer while the expression of IL-1b and IL-10 macrophages was measured by multiplex immunoassay on the LuminexTM 200. This study found a negative relationship between triglyceride/HDL ratio and expression of CD36-ABCA1+ macrophages. Ox-LDL stimulated macrophages showed insignificant differences in CD36+ABCA1- expression in non-T2DM and T2DM subjects (p=0.12) while CD36-ABCA1+ expression showed significant differences (p=0.04). Non-T2DM subjects showed high dominant CD36-ABCA1+ expression (72.7%) while T2DM subjects had low dominant expression (59.2%). The LPS and ox-LDL-stimulated macrophages showed different ratios of IL-1b/IL-10 in non-T2DM and T2DM subjects (p=0.05; p=0.02). T2DM subjects showed a higher IL-1b/IL-10 ratio than non-T2DM subjects. Analysis of the relationship between the IL-1b/IL-10 ratio and CD36-ABCA1+ macrophage expression showed a tendency for subjects with a high IL-1b/IL-10 ratio to have low CD36-ABCA1+ macrophage expression. The analysis also showed that 62% of T2DM subjects showed low expression of CD36- ABCA1+ macrophages with high IL-1b/IL-10 ratio and hsCRP above the median value, while 91% of non-T2DM subjects showed high CD36-ABCA1+ expression with IL-1b/IL-10  low and low hsCRP. In this study, it was found that there was a relationship between the expression of CD36-ABCA1+ macrophages and the ratio of IL-1b/IL-10 to hs-CRP which is a marker of cardiovascular disease risk.

Pendekatan sistem imun pada pejamu M. tuberculosismerupakan salah satu pilihan dalam pengembangan terapi tuberkulosis, terutama pada kasus tuberkulosis (TB)  resisten obat. Tujuan penelitian ini adalah untuk menganalisis perbedaan fungsi makrofag pada penderita TB resisten obat dibandingkan dengan kontak erat yang terinfeksi laten dan sehat. Sel Monosit Darah Tepi (SMDT) diisolasi dan dikultur selama 7 hari. Fagositosis dinyatakan jika terdapat minimal satu sel darah merah domba tampak melekat pada membran makrofag. Kemampuan lisosom diperiksa dengan uji aktivitas enzim fosfatase asam. Enam pasien TB-RO dan 18 kasus kontak erat (8 TB laten;10 sehat) di RS Universitas Indonesia direkrut sebagai subjek penelitian. Hasil menunjukkan bahwa aktivitas fagositosis kelompok infeksi laten lebih tinggi dibandingkan kelompok sehat dan TB RO (one-way ANOVA, p<0,05). Aktivitas enzim fosfatase asam lebih tinggi pada kelompok TB RO. Perbedaan fungsi makrofag ini diharapkan dapat menjadi referensi selanjutnya dalam terapi TB RO ataupun terapi pencegahan.  ......The immune system approach to the host of M. tuberculosis is an option in developing tuberculosis therapy, especially in drug-resistant tuberculosis (DR-TB) cases. This study aimed to analyze the differences in macrophage function in drug-resistant TB patients compared to close contacts who were latently infected and healthy. Peripheral Blood Mononuclear Cell (PMBC) was isolated and cultured for seven days. Phagocytosis is expressed when at least one sheep red blood cell appears attached to the macrophage membrane. The ability of lysosomes was examined by testing the activity of the acid phosphatase enzymes. Six DR-TB patients and 18 close contact cases (8 LTBI; 10 healthy) at Universitas Indonesia Hospital were recruited as research subjects. The results showed that the phagocytosis activity of the latent infection group was higher than that of the healthy and TB RO groups (one-way ANOVA, p<0.05). Acid phosphatase activity was higher in the DR-TB group. The difference in macrophage function is expected to be a further reference in DR-TB treatment or preventive therapy.

Based on the content of the galangal's essential oil which can be used as antimicroorganism, analgesic, and antiseptic characterized with inhibiting and destructing microorganism life process, it is predicted that there is a possibility of essential oil can be used for anti-inflammatory agent. Nitric-oxide (NO) is an unstable gas produced by cell such as macrophage and has the function as antimicroorganism. The aim of this study was to investigate whether essential oil of galangal components has an effect to the macrophage NO production, which stimulated by LPS E. coli. The both curative and preventive analysis using ANOVA showed that the NO productions differences were significant (p< 0,01). This study showed that the NO levels produced by murine macrophages induced by LPS E. coli were suppressed by essential oil in a dose dependent fashion, suggesting anti-inflammatory activities. Curatively, increased doses of the essential oil resulted in increased its anti-inflammatory functions. Five micro liter of the essential oil was preventively the most concentration as anti inflammation.

The purpose of this study was to evaluate the effectiveness of the essential oil of Kaempheria galangal as an anti-inflammatory agent, by evaluating its effect on interleukin 1B (IL-1B ???), produced by lipopolysaccharide (LPS) E. coli stimulated macrophages. Macrophage cells were stimulated with LPS E. coli and essential oil of Kaempheria galangal at concentrations of 3 ul/ml, 1.5 ul/ml, 0.75 ul/ml and 0.25 ul/ml. All of the treatment groups were incubated at 37°C in an atmosphere containing 5% CO2 for 24 hours. The concentrations of IL-1B supernatant were determined by using an enzyme-linked immunosorbent assay kit. Statistical analysis using ANOVA showed significant differences between the treatment groups (p<0.05). This study indicates that the essential oil of Kaempheria galangal suppressed IL-1B produced by LPS E. coli stimulated macrophage cells.
