T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.

|
|
T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.

Detailed explanation-1: -While B-cells produce antibodies to fight infection, T-cells protect people from getting infected by destroying cancerous and infected cells.
Detailed explanation-2: -T cells can wipe out infected or cancerous cells. They also direct the immune response by helping B lymphocytes to eliminate invading pathogens. B cells create antibodies. B lymphocytes, also called B cells, create a type of protein called an antibody.
Detailed explanation-3: -T cells are responsible for cell-mediated immunity. B cells, which mature in the bone marrow, are responsible for antibody-mediated immunity. The cell-mediated response begins when a pathogen is engulfed by an antigen-presenting cell, in this case, a macrophage.
Detailed explanation-4: -B cells recognize free, unprocessed antigens. T cells recognize antigens within a complex of cell surface proteins called the major histocompatibility complex (MHC) on the surface of antigen-presenting cells (also called accessory cells).
Detailed explanation-5: -While T cells possess only a cell surface form of the antigen receptor and require MHC and a presenting cell for antigen recognition, B cells produce a secreted version of their antigen receptor (termed antibody or immunoglobulin) which can bind directly to antigen.
