It?s a good time to learn the immune system?and this is the book for it

So much so that even Dettmer, who has dedicated his career to making obtuse scientific information accessible, decided that the best way to introduce immunity was in book form rather than through his online videos. There are sporadic disclaimers like this one:“Regulatory T cells are one of the parts of the immune system where things become very blurry. Receptors on cell surfaces are like noses the cell uses to sense its environment; lymph nodes are like speed-dating sites where cells from the innate immune system activate the appropriate cells from the adaptive immune system. In this comparison,  autoimmune diseases and allergies might result in part from the limited microbiomes we have in our modern, relatively sterile environments and fiber deficient diets—much like racist, sexist algorithms result from training on datasets comprising predominantly white faces.Dettmer likens people who eschew vaccines and prefer to gain immunity through “natural” infections to those going to a self-defense class where the instructors use real guns and swords.
