Effect of pIgR deletion on mouse body weight in B6 mice. Cohorts of age- and sex-matched male (closed circle, B6 n = 15; open circle, pIgR^−/− n = 10) and female (closed diamond, B6 n = 10; open diamond, pIgR^−/− n = 10) mice were weighed at indicated age. Shown are a body weight of individual mice at 4 weeks of age; and b mean ± SEM body weight over a 65-week time course. c Proportional weight gain is calculated as weight gained since 4 weeks of age as a percentage of 4-week body weight of the same mouse
