Which part of the immune system can most effectively eliminate influenza virus that has infected body cells?
We call this type of immunity adaptive---> natural----> active immunity. Here how it works: Adaptive immunity involves two classes of lymphocyte: B cells and T cells which work together in a coordinated system of adaptive immunity B cells-antibody-mediated (humoral) immunity T cells-cell-mediated (cellular) immunity Adaptive immunity occurs in a series of stages 1. Recognition of antigen (flu virus) 2. Activation of lymphocytes 3. Effector phase (immune attack) 4. Decline of antigen causes lymphocyte death (homeostatic balance) 5. Memory cells remain for later response if needed
What is the use of lymphocyte?
it is for immunity T-cell is for attack and B-cell is for anti body
What is the type of lymphocyte involved in nonspecific immunity?
natural killer cell
What is the job of the receptor proteins in a lymphocyte?
Receptor proteins in lymphocytes serve as critical components of the immune response by recognizing specific antigens, which are foreign molecules that trigger an immune reaction. These receptors, such as B cell receptors (BCRs) and T cell receptors (TCRs), bind to antigens with high specificity, initiating signaling pathways that lead to lymphocyte activation, proliferation, and differentiation. This process enables lymphocytes to identify and respond to pathogens, contributing to adaptive immunity.
What is the difference between autocrine signaling and endocrine signaling?
In autocrine signaling, a substance produced by a cell effects that cell, as with cytokines in the immunity system. Endrocrine signaling is a systemic response to a substance.
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 do IgE antibodies T cell receptors and MHC molecules have in common?
They are all players of your adaptive immunity.
What is the smallest WBC?
The smallest type of white blood cell (WBC) is the lymphocyte, specifically the small lymphocyte. These cells play a crucial role in the immune system, particularly in adaptive immunity, where they help recognize and respond to specific pathogens. Lymphocytes typically have a small size, with a diameter ranging from about 6 to 12 micrometers. They are essential for immune responses, including the production of antibodies and the destruction of infected cells.
How can cancer cells and virus infected body cells be killed before activation of adaptive immunity?
NK cell
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.
Adaptive immunity is produced by which cell?
There are many cells involved in adaptive immunity and requires them to work together for a fully functional adaptive response. These cells include: CD4 (Th1 & Th2) T cells, B cells (plasma and memory), professional antigen presenting (APC) cells that include: dendritic cell, B cells and macrophages.
What is the plural term for the word lymphocyte?
Lymphocytes is the plural of lymphocyte
