INTRODUCTION The immune function has been conceptually divided into innate and adaptive immunity. Innate immunity is not stand alone but interacts with adaptive immunity - Innate immunity primes adaptive responses - B cells are ‘primed’ by activated complement - Th1 cell differentiation needs pro-inflammatory cytokines - Adaptive responses enhance innate ‘effectors’ - Th1 promote macrophage phagocytosis + neutrophil killing - Antibodies act as opsonins and some activate complement Overview of Innate Immunity. - Motile cytokine/chemokines, phagocytose. associated with increase risk of progression to leukaemia.

Innate immunity and adaptive immunity are the two categories of the immune system of animals. The main difference between innate immunity and adaptive immunity is … molecules The innate immune system works rapidly (within minutes) and has broad specificity The adaptive immune system takes longer (days) and has exisite specificity Generation Times and Evolution Bacteria- minutes Viruses- hours Host- years The pathogen replicates and hence evolves millions of times faster than the host, therefore the host relies on a flexible and rapid immune response Out most polymorphic … PDF | On Feb 1, 2017, Salah M.

Therefore Immunity is defined as the state of resistance or in susceptibility to disease caused by particular microorganisms or their toxic products. - Eye = flushing of tears, lysozymes. The innate immune system is the most evolutionarily conserved arm of the immune system and it generates rapid, non-specific inflammatory responses in response to signals from Pattern Recognition Receptors (PRR).
