what are small proteins produced by T-cells
T helper 1 cells activate and assist in the activation of T cells by releasing signaling molecules called cytokines. These cytokines help stimulate T cells to multiply and become more effective in fighting off infections. Additionally, T helper 1 cells can directly interact with T cells to provide necessary signals for their activation and function.
T cells activate B cells by recognizing antigens on the surface of the B cells and releasing signaling molecules called cytokines. These cytokines stimulate the B cells to divide and produce antibodies to fight off the invading pathogens.
Helper T cells are important in the immune response because they play a crucial role in coordinating and regulating the activities of other immune cells. They help activate B cells to produce antibodies and stimulate cytotoxic T cells to kill infected cells, thus enhancing the body's ability to fight off infections and diseases.
T cells activate B cells in the immune response by releasing signaling molecules called cytokines. These cytokines stimulate the B cells to multiply and produce antibodies that target and destroy pathogens. This process helps the immune system to effectively fight off infections.
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.

These chemicals are called CYTOKINES.
Helper T cells help to activate T-cytotoxic cells and B-cells. For instance, if you become infected with a pathogen, a macrophage can consume that pathogen and then present parts of it on its own MHC (Major Histocompatability Complex) receptors. T helper cells then detect this and if this is a pathogen previously encountered, it can stimulate T-cytotoxic cells to begin attacking infected cells, and stimulate B-memory cells to begin rapidly dividing into B-plasma cells to produce anitbodies.
Specific response - 2 main types (cell mediated and antibody mediated immunity) may accompany or follow non specific reactions e.g. inflamation, but both rely on the actions of B and T lyphocytes. B cells make protein antibodies (gammaglobulins) that react against foreign proteins (antigens). T cells multiply and attack the pathogen. Cell Mediated Immunity - once a T cell recognises an antigen it multiplies rapidly. Helper T cells activate B cells to make antibodies, macrophages engulf the microbes along with any debris. Killer T cells attack the microbes and any infected body cells using strong powerful proteins (lymphokines). Suppressor T cells inhibit the response of other cells to the invading nicrobes.

Helper T cells, also known as CD4+ T cells, play a crucial role in activating killer T cells and B cells. Helper T cells recognize antigens presented by antigen-presenting cells, which triggers them to release signals that stimulate the activation and proliferation of killer T cells and B cells to mount an immune response against the specific pathogen.

Helper T-cells, also known as CD4+ T-cells, play a crucial role in activating B-cell lymphocytes during an infection. Helper T-cells release cytokines that stimulate B-cells to proliferate and differentiate into plasma cells, which produce antibodies to fight the infection.
T cells play a role in humoral immunity by helping B cells to produce antibodies. They do this by releasing cytokines that stimulate B cells to differentiate into plasma cells and memory B cells. T cells are also involved in regulating the strength and specificity of the antibody response.
HLA1 and HLA2 are not receptors themselves; they are human leukocyte antigen (HLA) proteins that present antigens to T cells. T cells have specific receptors, such as the T cell receptor (TCR), which recognize antigens presented by HLA proteins.
In the immune response, helper T cells (specifically CD4+ T cells) play a crucial role in triggering the production of B cells and cytotoxic T cells (killer T cells). When activated by antigen-presenting cells, helper T cells release cytokines that stimulate B cells to produce antibodies and enhance the activation and proliferation of killer T cells. This coordinated response is essential for effectively targeting and eliminating pathogens.
