Comparison

Active immunization with purified mouse… vs Immunization with bovine serum albumin

Implication

Renin immunization normalizes BP in SHR; leaves open human translation given autoimmune nephritis risk.

Structured PICO

Does active immunization with mouse renin reduce blood pressure in spontaneously hypertensive and normotensive rats?

P
Population
Male spontaneously hypertensive Okamoto-strain rats (SHR) and normotensive Wistar-Kyoto (WKY) rats (10 immunized per strain, plus controls)
I
Intervention
Active immunization with purified mouse submandibular gland renin
C
Comparator
Immunization with bovine serum albumin
O
Outcome
Blood pressuresurrogate

Active immunization against renin effectively lowers blood pressure and suppresses the renin-angiotensin system in spontaneously hypertensive rats, but induces chronic autoimmune interstitial nephritis.
