Technological advances in assay sensitivity have facilitated the identification of blood-based biomarkers of neurodegeneration and inflammation in human populations. The aim of this study was to translate these methods for use in male and female rhesus macaques across adulthood. We collected plasma samples from 47 rhesus macaques representing pre-adult (1–5 years, <em>n</em> = 6 female, <em>n</em> = 5 male), young (5–7 years, n = 5 female, <em>n</em> = 7 male), middle (8–16 years, n = 7 female, n = 7 male), and older adult (17–22 years, n = 6 female, <em>n</em> = 4 male) subjects.

Plasma NfL and IL-6 levels were significantly increased with age in both sexes, with a marked rise during middle adulthood. The ratio of Aβ42/Aβ40 was significantly lower in the middle and older aged females compared to the youngest group. There was no effect of age or sex on total tau or pTau181 levels.

Our study presents an intriguing divergence from the classical concept of immunosenescence, where aging has been assumed to cause poor antibody responses, reduced or inefficient vaccination, and overall blunted immune responses in elderly people. Our findings were opposite to some of these expectations; participants aged over 60 expressed elevated titers of anti-SARS-CoV-2 antibodies in comparison to younger adults. Analyzing the data of relative neutralization and avidity of anti-SARS-Cov-2 (S) antibodies we propose that although older adults produce a higher quantity of antibodies, their functional efficiency appears relatively reduced exhibiting lower neutralizing capacity and binding strength per antibody compared to younger adults. We can assume that the immune system of the elderly may require a higher level of antibody production to obtain a comparable level of protection. Our findings highlight the intricate nature of immune responses in convalescent older adults.

Animal models of fecal microbiota transplantation (FMT) were established in elderly and young rats. 16S rRNA sequencing revealed that the gut microbiota of the recipients shifted toward the profile of the donors, with concomitant cardiac structure and diastolic function changes detected via ultrasound and positron emission tomography–computed tomography (PET–CT). A group of significantly enriched myocardial metabolites detected by LC/MS were involved in the fatty acid β-oxidation process. Together with altered glucose uptake, as revealed by PET–CT, changes in ATP content and mitochondrial structure further verified a metabolic difference related to energy among rats transplanted with the gut microbiota from donors of different ages. This study demonstrated that gut microbes may participate in the physiological aging process of the rat heart by regulating oxidative stress and autophagy.
