What is responsible for cell-mediated immunity?
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.
What is the role of T cells in a human body?
T cells are part of the adaptive immunity. There are two major types of T cells: CD4+ T helper cells and CD8+ T cytotoxic cells. T helper cells primarily function in humoral immunity whereas T cytotoxic cells are important in cell mediated immunity. T helper cells produce cytokines to activate other immune system components like macrophages, B cells, etc. whereas T cytotoxic cells primarily kill infected cells.
How are helper t cells activated?
It is a type of leukocyte, or white blood cell, but it has no ability to ingest or destroy invading bacteria. It activates other white blood cells or antibodies to react with the invading organism.
May destroy infected cells select one a cytotoxic t cells b helper t cells c b cells d allergens e phagocytic cells?
T-cells will do this
Protects the body destroys bacteria and tumor cells?
T cells are made in the red bone marrow but specialize into t cells outside the marrow in the thymus, hence the T in Tcells. two types of t cells are cytotoxic effector cells and helper t cells. think of cytotoxic t cells as the drunk guy in the bar that wants to fight everyone (and is a good fighter by the way) and the helper t cells are the friends who show him who to fight and provides him with the weapons to fight. CTC can attach to and destroy cells carrying antigens Helper T cells 1. present antigen to CE cells and plasma B cells to activate them into action and 2. produe powerful immune protein called cytokins which can stimulate the lymphocyte cell disvision.
What cell is the most critical cell in immunity?
helper T cell
Which of the following cells is the most critical cell in immunity?
Helper T cell
What is the function of T-helper cells?
T cells destroy pathogens.
What is the function of the T helper cells?
T cells destroy pathogens.

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.
How do you beat the trespassers code in Ratchet and Clank?
use missles and shoot in the middle of the cannons then destroy the helper repairing ships.
What does humoral immunity involves?
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.
What do t cells do?
(t-cells) are involved in cell mediated immunity that can have memory of previous antigens(non self) that have invaded our body. cytotoxic tcells release preforin that destroy tumor cells or antigens helper tcells release cytokines/interlukins that help in more tcell differentiation
Which cells in the immune system identify pathogens and distinguish one pathogen from another?
B cells and Helper T cells
What do the helper t-cells activate?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
