Which of the following is/are true of antibody production?
|
|
Macrophages engulf and digest pathogens
|
|
|
The antigen of the pathogen is presented on the cell wall of the macrophage
|

|
The antigen on the pathogen attaches to an antibody on a T helper cell
|
|
|
T helper cells are activated when they attach to the specific antigen
|
Explanation:
Detailed explanation-1: -The helper T-cells release molecules called cytokines.
Detailed explanation-2: -T-cell dependent antibody responses require the activation of B cells by helper T cells that respond to the same antigen; this is called linked recognition.
Detailed explanation-3: -Follicular helper T (TFH) cells are a specialized subset of CD4+ T cells that provide help to B cells through both cell-cell interactions and release of cytokines, leading to the production of antibodies by B cells [1].
