Single CD4+ cells after Nippostrongylus brasiliensis infection.

We were interested in investigating the heterogeneity of CD4+ Th2 cells during infection response. In order to do so we injected Nippostrongylus brasiliensis (Nb) in recipient mice as this is known to elicit a Type 2 response. Mice were subcutaneously injected with Nb larvae and single CD4+ cells were isolated from mediastinal lymph nodes, mesenteric lymph nodes, and lungs 5 days after infection.
