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.

Antigen presentation. Coloured scanning electron micrograph (SEM) showing the interaction between a macrophage (red) and a T helper lymphocyte (Th cell, blue), two components of the body's immune system. Both are types of white blood cell. Macrophages are antigen-presenting cells (APCs). They present antigens (fragments on the surface of pathogens or foreign objects) to T lymphocytes, activating them. Each T lymphocyte recognises and binds to a specific antigen. Binding of the Th cell to the antigen presented by the macrophage activates the Th cell. This leads to its proliferation and the activation of other immune cells that eliminate the antigen.

One of the many cells tasked with keeping you alive: the cytotoxic T cell.

This graphic design is not meant as a comment on how devastating the effects of COVID-19 have been on so many, or how important vaccines and proper testing are; but rather to take a light-hearted look at a sign of our times and turn it around into something humorous. We all know someone who could relate to this message.

The right for all immunologists.

Antibodies in action. Artwork of antibodies (light to dark pink) in blood attacking an invading bacterium (left) and virus particle (centre right, green). Antibodies are Y-shaped proteins made by the immune system in response to infection by bacteria, viruses or allergens. Each antibody is made to recognise a specific target antigen and bind themselves to the surface. Binding can neutralize toxins or invading organisms and prevent them from interfering with normal cell processes. Binding can also make it easier for white blood cells to recognise and digest foreign particles.
