Witryna4 paź 2024 · Definition. B cells or B lymphocytes are part of the adaptive immune response. Once activated, these white blood cells produce antibodies. B lymphocytes have further roles as antigen-presenting cells and cytokine secretors. This cell type is classified into four main groups: transitional, naïve, plasma, and memory B cells. WitrynaIt may also serve an immune checkpoint molecule that inhibits antitumor immunity and promotes T cell exhaustion.

WitrynaLeucocyte immunoglobulin-like receptors subfamily B (LILRB) belongs to the type I transmembrane glycoproteins, which is the immunosuppressive receptor. LILRBs are widely expressed in bone marrow cells, hematopoietic stem cells, nerve cells and other body cells. Studies have found that LILRBs receptor can bind to a variety of ligands … WitrynaThe immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen. The main cells of the immune system are lymphocytes known as B cells and T cells.
