Differential Vβ T-Cell Receptor Usage during Chronic Experimental Schistosomiasis Corresponds with Distinct Pathological Presentations

CBA/J male mice with chronic Schistosoma mansoni infections display either moderate splenomegaly syndrome (MSS) or hypersplenomegaly syndrome (HSS). As MSS and HSS mice differ in several immunologic characteristics, we investigated T-cell receptor Vβ usage. The groups had significantly different expression of several Vβs, suggesting a relationship between the T-cell repertoire and schistosomiasis pathology.
