It is recognized by the CD40 protein on the B cell surface. The interaction between CD40 ligand and CD40 is required for helper T cells to activate B cells to proliferate and differentiate into memory or antibody-secreting effector cells. Individuals that lack CD40 ligand are severely immunodeficient.
Which cytokine is needed for the maturation of a functional helper T Cell. Do not circulate in blood. Some viruses, such as measles and herpes, are inaccessible to antibodies after the initial infection because they ... Regulatory T (Treg) Cells. Which T cell controls or limits the immune response to protect the hosts own tissue against ...
The importance of class I cytokines is evidenced by the role of the common cytokine receptor γ-chain (γ c) in T-cell development. X-lined severe combined immunodeficiency (SCID) occurs in individuals with mutations in the γ c chain that results in the absence of T cells and natural killer (NKT) cells, as well as nonfunctional B cells.
Oct 14, 2021 · Which cytokine is needed for the maturation of a functional helper T cell? a. IL-1 b. IL-2 c. IL-4 d. IL-12
In a type II Hypersensitivity reaction, when soluble antigens from infections agents enter circulation, tissue damage is a result of
Antibodies bind to the antigens on the cell surface
Binding to the toxins to neutralize their biological effects
The most important determinant of immunogenicity is the antigen's:
binding to the toxins to neutralize their biologic effects
If a person had very low levels of Ig__, that individual is more susceptible to infections of mucous membranes.
