Humoral immunity is a function of B cells. Circulating B cell numbers remain constant throughout the life span. However, there are subtle changes in the site of production. New B cells are generated in bone marrow. However, in aged animals an increased proportion of peripheral B cells is generated from self-renewing clones of CD5+ marginal zone ...
Humoral immunity account a significant role in the defense of extracellular microorganisms, mediated by antibodies (IgG, IgA, IgE, IgM, and IgD) produced by B lymphocytes, of which IgG accounts for 75 % of the total immunoglobulin in plasma (Zhang, Huang et al., 2018). While cellular immunity is mainly an immune response dominated by T cells.
Dec 12, 2008 · 3. Summary. Since the initial observation that B cells bear complement receptors, we have gained significant insight into how the complement system participates in adaptive immunity. Although this review has focused on humoral immunity, there is a growing understanding that complement also enhances T cell immunity.
Oct 4, 2022 · Mucosal humoral immunity in COVID-19. SARS-CoV-2 displays pulmonary tropism. Mucosal immune responses therefore probably play a crucial role in preventing the entry and spread of the virus Box 1 ...
Feb 2, 2023 · Innate Immunity — a Cellular Arm and a Humoral Arm. Cellular sensors of tissue damage, infection, and dysmetabolism are strategically localized on the cell surface, in the endosomal compartment, and in the cytoplasm, in both professional innate immune cells (i.e., those with innate immunity as their principal function) and nonprofessional innate immune cells (i.e., those with other principal functions).
Other articles where humoral immunity is discussed: human disease: The immune response: This type of response, called humoral immunity, is active mainly against toxins and free pathogens (those not ingested by phagocytes) in body fluids. A second type of response, called cell-mediated immunity, does not yield antibodies but instead generates T lymphocytes that are reactive against specific antigens. This defense is exhibited…
