Question

Which part of the adaptive immune response involves B cells? a. Neither humoral nor cell-mediated b. Humoral c. Cell-mediated d. Both humoral and cell-mediated

Answer 1

Answer:

Humoral immunity includes the B-cells.

Explanation:

There are two types of adaptive immunity responses. 1) cell mediated which possess of T cells

2) humoral immunity which possess of B-cells.

Humoral immunity is directed primarily against 1) toxin mediated diseases 2) certain viruses 3) infections in which virulence is related to polysaccharide capsules and to opsonize bacteria.

Role of B-cells in humoral immunity is

1) They differentiate into plasma cells and produce anitbodies

2) They are anitgen producing cells

B-cells are produced in fetal liver and in adukt life in bone marrow.

Later they are matured and undergoes through the process of clonal deletion as well.
