A, Incidence of keratitis as a function of age in B10.TCRδ−/− vs. wildtype B10 females. Mice from 4–7 different litters were examined at the indicated ages over the course of one year. B, Severity scoring system. C, Cohorts of female B10.TCRδ−/− littermates were scored for severity of keratitis every 2 weeks from 6 to 18 weeks of age; each group represents a cohort raised at one particular time. Each symbol represents an individual mouse. The total number of individuals in each cohort group is indicated in parentheses. The maximum possible score for an individual mouse is 10.
