It's day 7 of your Covid-19 infection: Each T cell that recognized the virus was activated and has been copying itself over and over again until a clone army is created. Listen to my latest podcast on T cells najjar.blog/2024/12/01/what-are-t-cells/

A Sisyphean T cell: One of your T cells recognizes a virus that does not infect humans. It will circulate endlessly between lymph nodes, touching countless dendritic cells but never finding its antigen. Listen to my latest podcast episode on T cells najjar.blog/2024/12/01/what-are-t-cells/

A naive B cell receives a vision from an oracle (T follicular helper cell), it now knows its destiny is not to fight infection. Instead, its fate is to be auto-reactive creating an autoimmune disease (myasthenia gravis), but first it must survive the negative selection #ImmunoSky #MedSky #RheumSky

I'm working on a podcast episode on types of T cells, I try to imagine different jobs or roles for each type, to make learning more fun. I imagined the T follicular helper cell as an oracle that appears in visions to B cells to tell them their destiny #ImmunoSky #RheumSky #MedSky
