Well there are several types of T cells, but they are all white blood cells
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.
Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.
T Cells
This process is called cell-mediated immunity. T cells, specifically cytotoxic T cells, recognize and destroy cells that are infected with a pathogen or abnormal cells, such as cancer cells. This immune response is crucial for clearing infections and providing immunity against future exposures to the same antigen.
T-cells and B-cells are both initially made in the bone marrow. T-cells mature in the thymus. They both freely float around in all lymph nodes and the various lymph organs (e.g., tonsils, spleen...).
it produces antibodies that circulate in body fluids.
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.

No, it's cellulair. Handy to be recognized by the cytotoxic T-cells.
Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.
T cells are specifically responsible for cell-mediated immunity. They include cytotoxic T cells, helper T cells, and regulatory T cells, each playing a crucial role in orchestrating the immune response against pathogens or abnormal cells.
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.
The cells which are involved in the production of antibodies are known as B cells. These are effector cells which will secrete anybodies and activate the antigens.
humoral 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.
ANTIBODY IMMUNITY IS BETTER TERMED AS HUMORAL IMMUNITY Humoral immunity is acquired by B-lymphocytes and T-helper lymphocytes as An antigen is engulfed by antigen processing cell (APC) e.g. , B-cells then a part of an antigen (epitope) is presented to T-helper cells in association with MHC-II (MAJOR HISTOCOMPATIBILITY COMPLEX) then T-helper cell activates B-cell to produce effector cell (plasma cell) and memory cell then plasma cell secrete antibodies which neglify harmful or toxic effects of the above antigen. CELL MEDIATED IMMUNITY Every cell of the body can show this response while in the above case only APC can show humoral response A whole foreign body/ antibody is engulfed by the cell then epitope is represented to cytotoxic T-lymphocytes(CTLs) then CTLs secrete certain chemicals which kill the cell along with foreign body.
Lymphocytes have a <protective role>. Particular function depends on the type of lymphocytes. T cells are involved in cell-mediated immunity whereas B cells are primarily responsible for humoral immunity (relating to antibodies). Protective functions are done through: lysis of virually infected cells or tumor cells, realease of cytokines and growth factors to stimulate otherimmune cells, immunoregulation and cytotoxicity, destruction of virally infected cells, secretion of antibodies
