Part I. Innate Immunity

Innate + adaptive immunity Innate immunity only From Thomas C. G. Bosch (Kiel)

Histoire dune découverte « The dirty little trick »

A paradigm: Self vs. Non-self « The structure of scientific revolutions » Thomas S. Kuhn « Their achievement was sufficiently unprecedented to attract an enduring group of adherent away from competing modes of scientific activity » - « Simultaneously, it was sufficiently open-ended to leave all sorts of problems for the redefined group of practitioners to resolve »
