The secondary response of humoral immunity
WebAn immune response is a reaction which occurs within an organism for the purpose of defending against foreign invaders. These invaders include a wide variety of different microorganisms including viruses, bacteria, parasites, and fungi which could cause serious problems to the health of the host organism if not cleared from the body.

The secondary response of humoral immunity
Did you know?
WebB cells are lymphocytes that play a large role in the humoral immune response (as opposed to the cell-mediated immune response, which is governed by T cells). B cells primarily function to make antibodies against antigens, act as antigen-presenting cells (APCs), and eventually develop into memory B cells to provide long-term immunity. WebThe secondary response develops more quickly and produces higher and more sustained levels of antibody with higher affinity for the specific antigen. 18.5 Vaccines Adaptive immunity can be divided into four distinct classifications: natural active immunity, natural passive immunity, artificial passive immunity, and artificial active immunity.
WebApr 14, 2024 · 2.2 Humoral immunity. To elucidate the humoral immune responses induced by these vaccine formulations, SmT1-R and SmT1-O antigen-specific IgG titers in serum collected on Day 28 were assessed by ELISA. Overall, SLA-adjuvanted SmT1-O elicited a geometric mean titer (GMT) of 423,817 – 614,699 against SmT1-R, whereas AddaS03 … WebSep 15, 2010 · The humoral response, mediated by B cells with the help of T cells, produces high-affinity and antigen-specific antibodies. This is in contrast with the CD8 T-cell response which leads to the generation of large numbers of antigen-specific cells that are capable of directly killing infected cells.
WebHumoral immunityis the process of adaptive immunity manifested by the production of antibodies by B lymphocytes. It develops in bone marrow. B cells may be triggered to proliferate into plasma cells. Plasma cells produce antibodies. Antibodies are produced when the antigen bonds the B cell receptor (BCR). Some B cells produce memory cells.
