Macrophage engulfing bacterium. Artwork of a section through a macrophage (center) engulfing a bacterium (bottom). The macrophage pseudopod is seen here extending over the bacterial cell wall (green) and flagellum. Within the bacterium can be seen its cytoplasm (purple) and nucleus (red and orange). Above is the blood serum (yellow and brown). Macrophages are a type of white blood cell (leucocyte) which defends the body against invading micro-organisms. When a macrophage encounters a pathogen, it engulfs and destroys it, a process called phagocytosis. This image is the third in a series of three. See also P276/201 & P276/202.

T lymphocytes and cancer cell. Coloured scanning electron micrograph (SEM) of T lymphocyte cells (pink) attached to a cancer cell. T lymphocytes are a type of white blood cell that 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. The genetic changes that cause a cell to become cancerous lead to the presentation of tumour antigens on the cell's surface. Magnification: x2300 when printed at 10 centimetres wide.

Neutrophil engulfing MRSA. Coloured scanning electron micrograph (SEM) of a neutrophil white blood cell (bottom) engulfing methicillin-resistant Staphylococcus aureus bacteria (MRSA, yellow). This process is called phagocytosis. MRSA is a round (coccus) Gram positive bacterium that is resistant to many commonly prescribed antibiotics. Neutrophils are the most abundant white blood cell and are part of the body's immune system.

Illustration showing two types of T-cells (green and purple spheres) binding to a cluster of three cancer cells (centre, red and grey spheres). T cells, or T lymphocytes, are components of the body's immune system. T cell receptors recognise and bind to peptides (chain of spheres) presented by class I MHC (major histocompatibility complex) molecules on the surface of the cancer cell. This activates the T cell, which releases lytic granules that penetrate and kill the cancer cell.

Another way of showing off our immune compromised bodies with a bit of style from the Galaxy.

T-lymphocytes, illustration. T lymphocytes, or T cells, are a type of white blood cell and components of the body's immune system. They mature in the thymus. T lymphocytes recognise a specific site on the surface of pathogens or foreign objects (antigens), bind to it, and attract antibodies or cells to eliminate that antigen.

Guardian Of Health Shield Design features a strong and protective symbol, representing safety and well-being. Perfect for those who value their health and want to stay protected.

Natural killer (NK) cell, illustration. NK cells are a type of white blood cell and a component of the immune system. They recognise certain proteins, or antigens, on virus-infected or tumour cells and destroy them.

The right for all immunologists.

Get to know your immune system with this cool blood cell design. The white blood cell types are granulocytes (neutrophils, eosinophils & basophils), monocytes and lymphocytes. Wear this if you are into biology, hematology, immunology or medicine because a healthy immune system is important.
