Anergy and suppression in B-cell responses

Two main ideas have been put forward to explain the unexpectedly low anti-hapten antibody titres which can result from pre-priming a mouse with carrier before hapten-carrier immunization. The first involves the interaction of a network of idiotype-specific suppressor T cells, the second instead arguing for the role of intrinsic B-cell anergy. This paper proposes that the data available can equally be interpreted as reflecting the suboptimal interaction between T and B cells at differing stages of maturity, provided that memory B cells can be divided into two subsets. Further, it is suggested that these considerations must be taken into account in the analysis of B-cell anergy in receptor transgenic mice.
