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.
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.
Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.
Mediators of humoral immunity include antibodies, which are produced by B cells and circulate in the bloodstream. These antibodies can recognize and bind to specific antigens, marking them for destruction by other immune cells. In addition, cytokines released by activated B cells and helper T cells help regulate the immune response and stimulate antibody production.

Humoral
Antibody-mediated response, also known as humoral immunity, is a crucial aspect of the adaptive immune system where B cells produce antibodies in response to specific antigens. These antibodies bind to pathogens such as bacteria and viruses, neutralizing them or marking them for destruction by other immune cells. This response is essential for providing long-lasting immunity and is the basis for the effectiveness of many vaccines. It plays a vital role in protecting the body against infections and diseases.
humoral immunity response
This statement is not accurate. Pathogens can provoke both cell-mediated and antibody-mediated responses at the same time. The type of immune response generated depends on the specific characteristics of the pathogen and the immune system of the host.
Cytokines
T lymphocytes (T cells) are the cell type that interacts with both humoral and cell-mediated immune pathways. They help orchestrate immune responses by recognizing antigens presented by antigen-presenting cells and signaling other immune cells to either produce antibodies (in the case of B cells) or kill infected cells directly.
Helper T cells
The extracellular spaces are protected by the humoral immune response, in which antibodies produced by B cells cause the destruction of extracellular microorganisms and prevent the spread of intracellular infections. This is often called antibody mediated immunity. This response is triggered by an antigen and usually requires helper T cells.
