Cancer malignant cells - 3d rendered image, abstract enhanced scanning electron micrograph (SEM) of cancer malignant cells. Visual of overall shape of the cell's surface at a very high magnification. Medical research concept.

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.

Cancer cells vis - 3d rendered image, enhanced scanning electron micrograph (SEM) of cancer cell. Visual of overall shape of the cell's surface at a very high magnification. Medical research concept.

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.

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.
