Circadian and circannual aspects of the complement cascade - new and old results, differing in specificity.
Single cosinor analyses of several elements in the complement cascade suggest the occurrence of circadian rhythms in this immunochemical system. Some earlier results, obtained with less specific methods and reported as properdin, on reanalysis also reveal circadian and circannual rhythms in the aspects of immunology represented. The topic of the complement cascade as a whole is briefly reviewed in the content of modern knowledge.
