Abstract:
Aging is a significant risk factor for disease in several tissues, including the prostate. Defining the kinetics of age-related changes in these tissues is critical for identifying regulators of aging and evaluating interventions to slow the aging process and reduce disease risk. An altered immune microenvironment is characteristic of prostatic aging in mice, but whether features of aging in the prostate emerge predominantly in old age or earlier in adulthood has not previously been established. Using highly multiplexed immune profiling and time-course analysis, we tracked the abundance of 29 immune cell clusters in the aging mouse prostate. Early in adulthood, myeloid cells comprise the vast majority of immune cells in the 3-month-old mouse prostate. Between 6 and 12 months of age, there is a profound shift towards a T and B lymphocyte-dominant mouse prostate immune microenvironment. Comparing the prostate to other urogenital tissues, we found similar features of age-related inflammation in the mouse bladder but not the kidney. In summary, our study offers new insight into the kinetics of prostatic inflammaging and the window when interventions to slow down age-related changes may be most effective.
