National Library of Medicine Cameron AM, et al. 2015;20:44124. Therefore, in the absence of TFH cells, similar to B cell activation by T-cell independent antigens, a quick burst of low affinity plasma cell production is formed but this does not lead to germinal center induction nor permit antibody affinity maturation or the differentiation of effective memory B cells which are essential in fortifying the body against subsequent infections. optimal timing and the speed of contrast injection.
