Complement dependence of localisation of aggregated IgG in germinal centres

Scand J Immunol. 1975;4(4):343-47. doi: 10.1111/j.1365-3083.1975.tb02635.x.

Abstract

In vivo decomplementation of mice with cobra factor completely prevented trapping of aggregated human IgG within splenic germinal centres. Observations of the intrasplenic position of the aggregated material within 8 hr of its injection into normal and decomplemented mice suggest that the early phase of localisation in germinal centres depends on binding to lymphocyte C3 receptors.
