T lymphocytes and cancer cells, SEM
T lymphocytes and cancer cells. Coloured scanning electron micrograph (SEM) of T lymphocyte cells (purple) attached to cancer cells. T lymphocytes are a type of white blood cell and one of the components of the bodys immune system. They recognise a specific site (antigen) on the surface of cancer cells or pathogens and bind to it. Some T lymphocytes then signal for other immune system cells to eliminate the cell. Cytotoxic T lymphocytes eliminate the cell themselves by releasing a protein that forms pores in the cells membrane. The genetic changes that cause a cell to become cancerous lead to the presentation of tumour antigens on the cells surface. Magnification: x1600 at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate relationship between T lymphocytes and cancer cells. In this false-colored scanning electron micrograph, we witness the battle between these purple-hued T lymphocyte cells and their malignant counterparts. T lymphocytes, a vital component of our immune system, possess an extraordinary ability to recognize specific sites or antigens on the surface of cancer cells or pathogens. Once identified, they bind to these targets and initiate a cascade of events aimed at eliminating the threat. In this image, we observe T lymphocytes firmly attached to cancer cells as they carry out their mission. Some T lymphocytes signal other immune system cells to join forces in eradicating the dangerous cell. Remarkably, cytotoxic T lymphocytes take matters into their own hands by releasing a protein that forms pores in the cancer cell's membrane - ultimately leading to its demise. The genetic changes responsible for transforming normal cells into cancerous ones result in tumor antigens being presented on their surface. This triggers an immune response from vigilant T lymphocytes who swiftly recognize and engage with these antigens. With a magnification level of x1600 at 10 centimeters wide, this visually striking SEM print offers us a glimpse into the microscopic world where medicine meets artistry. It serves as a powerful reminder of our body's remarkable defense mechanisms against malignancy while highlighting ongoing research in oncology and immunology fields striving for breakthroughs in fighting against diseases like cancer.
