We examined whether immunization with the nonpathogenic strain R-15 of herpes simplex virus-1 (HSV-1) may prevent the clinical and neuroendocrine changes induced by the pathogenic HSV-1 strain Syn17+. Inoculation of strain Syn17+ to control rats induced fever, marked motor hyperactivity and aggressive behavior, and increased serum ACTH, corticosterone (CS) and brain prostaglandin-E2 production. Mortality was 100%. Immunization with strain R-15 prior to challenge with Syn17+ induced the production of neutralizing antibodies to HSV-1 Syn17+, and abolished the above clinical and neuroendocrine changes. Mortality was completely prevented. These results indicate that immunization with HSV-1 strain R-15 protects rats from lethal HSV-1 encephalitis and prevents its clinical and neurochemical manifestations.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D003345 Corticosterone An adrenocortical steroid that has modest but significant activities as a mineralocorticoid and a glucocorticoid. (From Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1437)

D000324 Adrenocorticotropic Hormone An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
