The b cells are specifically responsible for cell mediated immunity.
There are two types of immunity Humoral & Cell-mediated ; in humoral immunity plasma cells produces specific antibodies against a particular antigen that may invade the boby.
The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.

In cell mediated immunity the lymphocytes go and attack the offending microorganism. This develops after about 2 to 3 weeks after the first attack by microorganisms.

Actually acquired immunity consists of "humoral immunity" and "cell mediated immunity. Acquired immunity is the same with adaptive immunity, it is when the antibodies are produced within the bodies after the exposure of pathogen. Humoral immunity secreted antibodies while cell mediated immunity involves in production of T lymphocytes.
Humoral immunity is mediated by antibodies.
The basic principles are; antibodies will be produced in any signs of infection, or abnormality. Then these antibodies are desiged specifically to target, and bind to specfic antigens.

T cell mediated immunity and B cell immunity (Antibody secretion.
The b cells are specifically responsible for cell mediated immunity.
Antibodies can cause rejection of the donor organ/ tissue within minutes if the person receiving the organ already had antibodies against the donor. Rejection of donated blood involves antibodies which form the basis of the immune response triggered by the donation. Rejection of a donated kindey or heart involves both antibodies and cell mediated immunity.
Humoral immunity is effected by antibodies produced by plasma cells toward a specific foreign antigen. Cellular immunity does not directly involve antibodies, but refers to cellular destruction of alien cells/tissues by production of cytotoxins locally, typically the latter are produced by T-lymphocytes and natural killer cells.

Active immunity involves the production of antibodies (by B lymphocytes) and cell-mediated response (with T lymphocytes). It renders relatively longer immunity (compared to passive immunity). Active immunity may be natural or artificial.This type of active immunity is said to be natural because the immunity is induced not by deliberate exposure (such as vaccination). The individual has developed immunity to a live pathogen by having been exposed to it and by developing a primary immune response that led to immunological memory.
