Macrophage and dendritic cell (DC) populations residing in the intestinal lamina propria (LP) are highly heterogeneous and have disparate yet collaborative roles in the promotion of adaptive immune responses towards intestinal antigen. Under steady-state conditions, macrophages are efficient at acquiring antigen but are non-migratory. In comparison, intestinal DC are inefficient at antigen upta...

Background. Determination of Rh-affiliation is mandatory for donors and recipients, surgical patients, pregnant women, etc. There are variants the D antigen that difficult to identify by serological methods, example, a weak antigen.
 Aim. using genotyping in cases, when use methods does not allow obtaining reliable result.
 Material methods. We studied blood samples from (n=18), women...

Pengabdian masyarakat ini dilakukan seiring dengan penambahan jumlah kasus COVID-19 berlangsung cukup cepat dan sudah terjadi penyebaran antar negara. Berdasarkan bukti ilmiah, dapat menular dari manusia ke melalui percikan batuk/bersin (droplet). Orang yang paling berisiko tertular penyakit adalah orang kontak erat pasien termasuk merawat COVID-19. Metode digunakan dalam kegiatan menggunakan b...

K46J B lymphomas express a T cell costimulatory activity that is not inhibited by CTLA-4Ig, anti-B7-1, anti-B7-2, anti-intercellular adhesion molecule 1 or antibodies to heat stable antigen. In this paper we report that this costimulatory activity is mediated at least in part by 4-1BB ligand, a member of the tumor necrosis factor (TNF) gene family that binds to 4-1BB, a T cell activation antige...

The effect of interferon on simian virus 40 (SV40) and adenovirus 2 (Ad2) T antigen synthesis has been examined in cells infected with SV40, with Ad2, and with a nondefective Ad2-SV40 hybrid virus, Ad2(+)ND(4). The induction of SV40 T antigen by SV40 was highly sensitive to interferon, whereas the induction of Ad2 T-antigen by Ad2 was resistant. This difference in interferon sensitivity was als...

Abstract CD154 pathway blockade has been shown to significantly improve graft survival in transplantation. Recently, CD11b was identified as an alternate receptor for CD154. CD154:CD11b interactions promote rejection by increasing the recruitment of innate and adaptive immune cells into allograft. However, effects on protective response infection during immunosuppression not elucidated. To addr...

Background: The therapy of leishmania infection is difficult and each year 1.5 million new cases of cutaneous leishmaniasis and 500,000 new cases of visceral leishmaniasis are estimated, therefore, there is a need for an effective vaccine. Monoclonal antibody (mAb) is one of the suitable methods for isolation and purification of leishmania antigens. In this report, we produced several mAb aga...

Autoimmune diseases (ADs) are characterized by the production of autoreactive lymphocytes, immune responses to self-antigens, and inflammation in related tissues organs. Cytotoxic T-lymphocyte antigen 4 (CTLA-4) is majorly expressed activated T cells works as a critical regulator inflammatory response. In this review, we first describe structure, expression, how signaling pathways CTLA-4 partic...
