Meningo-encephalitis accompanying retinochoroiditis in a murine model of congenital toxoplasmosis
A histopathological study of the brains of adult mice infected in utero with Toxoplasma gondii and presenting manifestations of ocular toxoplasmosis is reported. All brains contained Toxoplasma tissue cysts. A sub-acute/chronic meningo-encephalitis was the main feature of the inflammatory response in the brain. Microscopical features suggest that autoimmune processes may play a part in the disease. We suggest that our mouse model will provide a simple and inexpensive tool for the investigation of histopathological processes in the CNS resulting from congenital Toxoplasma infection

Gene-age interactions in blood pressure regulation: A large-scale investigation with the CHARGE, global BPgen, and ICBP consortia
Although age-dependent effects on blood pressure (BP) have been reported, they have not been systematically investigated in large-scale genome-wide association studies (GWASs). We leveraged the infrastructure of three well-established consortia (CHARGE, GBPgen, and ICBP) and a nonstandard approach (age stratification and metaregression) to conduct a genome-wide search of common variants with age-dependent effects on systolic (SBP), diastolic (DBP), mean arterial (MAP), and pulse (PP) pressure. In a two-staged design using 99,241 individuals of European ancestry, we identified 20 genome-wide significant (p≤ 5 10) loci by using joint tests of the SNP main effect and SNP-age interaction. Nine of the significant loci demonstrated nominal evidence of age-dependent effects on BP by tests of the interactions alone. Index SNPs in the EHBP1L1 (DBP and MAP), CASZ1 (SBP and MAP), and GOSR2 (PP) loci exhibited the largest age interactions, with opposite directions of effect in the young versus the old. The changes in the genetic effects over time were small but nonnegligible (up to 1.58 mm H
