2019 Poyntz H, Jones A, Jauregui R, Young W, Gestin A, Mooney A, Lamiable O, Altermann E, Schmidt A, Gasser O, Weyrich L, Jolly C, Linterman M, LeGros G, Hawkins E, Forbes-Blom E. Genetic regulation of antibody responsiveness to immunization in substrains of BALB/c mice To help elucidate the heterogeneity of vaccine responsiveness amongst humans, different substrains of mice are investigated. Notably, antibody response phenotypes are not altered by microbiota composition, and differentially sourced mice have significant variation in their humoral immune responses.
