White blood cells, more specifically B-lymphocytes.
Cell-mediated immunity is primarily carried out by T cells, specifically cytotoxic T cells and helper T cells. These T cells are responsible for recognizing and targeting infected or abnormal cells in the body, helping to destroy pathogens and mount an immune response.
humoral immunity
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.
Specific immunity is also known as adaptive immunity or acquired immunity active or passive. There are two types of specific immune responses; humoral and cell mediated. Humoral immunity is mediated by B Lymphocytes that produce antibodies; forms of B lymphocytes are IgG, IgM, IgA, IgE. They primarily attach bacterial invaders Cellular immunity is mediated by T Lymphocytes and combat intracellular infections (such as viruses), monitor cellular disruptions like tumors or foreign tissues, and fight fungal infections.
Thymus Gland
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
The white blood cells primarily responsible for adaptive immunity are lymphocytes, specifically B cells and T cells. B cells are responsible for producing antibodies that target specific pathogens, while T cells are involved in directly killing infected cells and coordinating the immune response. Together, they provide a tailored and long-lasting defense against specific antigens.
thymus
Lymphocyte is a type of white blood cell found in the vertebral immune system. Lymphocytes can be divided into Large lymphocytes and small lymphocytes when viewed under the microscope. The Large lymphocytes include natural killer cells (NK cells) There are mainly two types of Lymphocytes. T Lymphocytes and B Lymphocytes. (these are small lymphocytes according to the microscopic view) B Lymphocytes have 3 subsets. You can see the attached link for further information.
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.
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.
