Activated T helper cells segregate the cytokines IL-4, IL-5, IL-6, IL-9, IL-10 and IL-13, leading to B cell antibody class switching, activation of cytotoxic T cells, and maximazing the bactericidal activity of phagocytes such as macrophages. Source: PDB entries 2B8U, 3VA2, 1ALU, 2H24, 3BPO

The antigen (light green) is a peptide from a tumor cell, bacteria or virus. Dendritic cells present antigens to lymphocytes through their membran bound MHC-molecules (orange). After binding to the MHC-antigen complex, the T-cell receptor (violet) sends a signal cascade into the T-lymphocyte cell, that activates an immune response.

T cells play a key role in the development of long-term immunity. to coronavirus. Helper T cells stimulate B cells and other immune cells, whereas killer T cells target and destroy infected cells.

Lymphocyte produced by the thymus gland and actively participating in the immune response.

Engineered receptors on the surface of a T-lymphocyte bind specifically to CD19-antigen molecules on the surface of a leukemia cell. This activates a signal cascade in the T-cell leading to the segregation of vesicles that contain perforin and gramzymes molecules. The perforins build channels for the granzymes which enter the leukemia cell and activate finally the apoptosis (cell death) of the cancer cell.

Natural killer cells are a type of lymphocytes which destroy cancer cells and other altered cells releasing cytotoxic granules.

Dendritic cells are antigen-presenting cells of the immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system. They are messengers between the innate and the adaptive immune systems.

A single neutrophil white blood cell in the artery with red blood cells floating around it within the artery. Neutrophil is the most abundant of the white blood cells within mammals.

T-cell receptor in complex with the MHC class II-peptide complex. The antigen (light green) is a peptide from a tumor cell, bacteria or virus. Dendritic cells present antigens to lymphocytes through their membran bound MHC-molecules (violet). CD4 molecules (light blue) bind to other portions of the MHC, strengthening the interaction. After binding to the MHC-antigen complex, The T-cell receptor (blue) sends a signal cascade through an attached G-protein into the T-lymphocyte cell, that activates an immune response.

Therapeutic medical procedure referral - Monoclonal antibody therapy

On a medical record form, a pen rests on the section where Virology blood tests to be ordered are recorded. These blood tests relate to HIV and AIDS.

The antigen (light green) is a peptide from a tumor cell, bacteria or virus. Dendritic cells present antigens to lymphocytes through their membran bound MHC-molecules (orange). After binding to the MHC-antigen complex, the T-cell receptor (violet) sends a signal cascade into the T-lymphocyte cell, that activates an immune response.

Immunologically active proteins on a T-cell. TCR (blue), CD-4 (light blue), CD-28 (dark blue), PD-1 (magenta), CTLA-4 (violet), Ca-channel (dark violet). The T-cell receptor, CD-4 and CD-28 activate T-cells, while PD-1 and CTLA-4 inhibit the activation of T-cells.
