T cell development - the evolution of an assassin

This photograph originally appeared in the 2018 Research student photography and image competition held to celebrate National Science Week (11-19 August 2018). Blurb: T cell is a type of white blood cells, which play critical role in cell mediated immunity. They develop in an organ, called, the thymus. The fluorescence image captures a time-point at which, the T cell (yellow and magenta-Small cell) docks onto a thymic cell (blue-large cell), where the thymic cell provides the T cell with the essential cues needed for its proper development and maturation. Aberrant T cell development can cause immune deficiency diseases and cancer
