It's easy to find general lists of immune systems: innate/adaptive, complement, phagocytes, B/T cells, and so on. Annoyingly, they are very skimpy on quantitative information regarding the speed of these reactions and that matters a lot.
I'm wondering how long after for example bacteria entering the body, do immune systems kick into action? I'm guessing the complement, clotting, and local phagocytes are the fastest but I could not find actual times required.
I found speeds for some immune systems but not for most. This recent recent study on the immune reaction against SARS-CoV2 has a rough time course with dendritic cells early and antibodies from activated B cells in weeks. This more detailed time course, also for Covid, shows the IgM peak at around 2 weeks ("The majority of patients appeared to have seroconverted by day 14").
Ok, but what about all the other processes? How fast can an innate immune cell hone in via chemotaxis, how fast are T killer cells on the scene upon viral infection, how fast is the complement or clotting cascade really, how does antibody production vary in speed between triggers and individuals? I hope you can point me towards any data that might shed light on this. I appreciate any leads.
