Which of the following cells is the most critical cell in immunity?

The most critical cell in immunity is the T lymphocyte (T cell). T cells play a key role in coordinating immune responses by recognizing and attacking infected cells and regulating other immune cells.


Is Acquired Immunity the same as Humoral Immunity?

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.


What gland plays a major role in the development of immunity?

The thymus gland plays a major role in the development of immunity. It is responsible for the maturation of T cells, which are a type of white blood cell that plays a critical role in the immune response.


Why is LY number important in your blood test?

T cell mediated immunity and B cell immunity (Antibody secretion.


The second most abundant substance in the human body and a vital part of every cell?

Proteins are the second most abundant substance in the human body and are essential for the structure, function, and regulation of all cells. They play a critical role in various biological processes such as growth, repair, and immunity.


The T cells are responsible for 1 humoral immunity 2 cell-mediated immunity 3 generalized immune response 4 allergies?

Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.

What cells types are specifically responsible for cell mediated 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.


What are the differences between humoral immunity and cellular immunity?

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.


What are the difference between antiviral immunity and anti bacterial immunity?

Antiviral immunity targets viruses by recognizing viral antigens and activating immune responses specific to viral infections. Antibacterial immunity targets bacteria by recognizing bacterial antigens and activating immune responses specific to bacterial infections. The mechanisms of immune cell activation, the types of cells involved, and the specific responses generated differ between antiviral and antibacterial immunity.
