Observations

Despite a higher MRDT [0058], rhesus macaques appear to age significantly faster than humans do from a physiological perspective [0002]. The females of this species reach menopause at about the age of 25 [0434]. Four male monkeys under caloric restriction for part of their lives and one fed a normal diet have lived beyond 40 years [1074].

Old animals suffer from various age-related diseases common in humans, including heart disease and cancer; amyloidosis, diabetes and, in females, endometriosis have also been reported [0981]. Chinese rhesus macaques have demonstrated noticeable age-related changes in both T and B cell subsets, comparable to those found during human ageing. T cell ageing is slower in female Chinese rhesus macaques than in males, giving males a more severe immune risk profile [1183]. There have been conflicting reports on the effects of caloric restriction in rhesus macaques. One ongoing study first reported in 2009 that caloric restriction can lower the incidence of ageing-related deaths [0873], a second ongoing study reported in 2012 that caloric restriction did not improve survival even if beneficial health effects were observed [1074]. The former ongoing study reported again in 2014 that caloric restriction reduces age-related and all-cause mortality [1184]. A comprehensive assessment of longitudinal data from both sites concluded that caloric restriction does improve health and survival of rhesus monkeys [1257].
