+ Step 1 – Innate Immune Response n For most infectious diseases, the first response is the “innate immune response”. n This is a nonspecific response to any pathogen, usually including the signs of inflammation (heat, redness, swelling, pain). n Along with this response comes the secretion of natural defense mediators, such as the prostaglandins, arachadonic acid metabolites, etc. n This is a general response and is not specific for any pathogen.
