Arterial hypertension was induced in WT (C57BL6/J) and cell-specific CD40(L) knockout mice (AdipoqCre x CD40 fl/fl, CD4Cre x CD40 fl/fl, CD19Cre x CD40 fl/fl, and GP1baCre x CD40L fl/fl) via angiotensin (AT-II) infusion (1 mg/kg/d) for seven days. The gene discussed is CD40; the disease is Hypertension.
