Aging is linked to deficiencies in immune responses and increased systemic inflammation. To unravel the regulatory programs behind these changes, we applied systems immunology approaches and profiled chromatin accessibility and the transcriptome in PBMCs and purified monocytes, B cells, and T cells. Analysis of samples from 77 young and elderly donors revealed a novel and robust aging signature in PBMCs, with simultaneous systematic chromatin closing at promoters and enhancers associated with T cell signaling and a potentially stochastic chromatin opening mostly found at quiescent and repressed sites. Combined analyses of chromatin accessibility and the transcriptome uncovered immune molecules activated/inactivated with aging and identified the silencing of the IL7R gene and the IL-7 signaling pathway genes as potential biomarkers. This signature is borne by memory CD8+ T cells, which exhibited an aging-related loss in binding of NF-κB and STAT factors. Thus, our study provides a unique and comprehensive approach to identifying candidate biomarkers and provides mechanistic insights into aging-associated immunodeficiency.

The enormous genetic diversity and mutability of HIV has prevented effective control of this virus by natural immune responses or vaccination. Evolution of the circulating HIV population has thus occurred in response to diverse, ultimately ineffective, immune selection pressures that randomly change from host to host. We show that the interplay between the diversity of human immune responses and the ways that HIV mutates to evade them results in distinct sets of sequences defined by similar collectively coupled mutations. Scaling laws that relate these sets of sequences resemble those observed in linguistics and other branches of inquiry, and dynamics reminiscent of neural networks are observed. Like neural networks that store memories of past stimulation, the circulating HIV population stores memories of host–pathogen combat won by the virus. We describe an exactly solvable model that captures the main qualitative features of the sets of sequences and a simple mechanistic model for the origin of the observed scaling laws. Our results define collective mutational pathways used by HIV to evade human immune responses, which could guide vaccine design.

The new competencies of psychoneuroimmunoendocrinology and psychoneuroimmunology play a strategic role in interdisciplinary science and interdisciplinary planning and decision-making. The introduction of multi-vector neurotechnologies of artificial intelligence and the principles of digital health care will contribute to the development of modern neuroscience and neuromarketing. The availability of innovative technologies, such as next-generation sequencing and correlated bioinformatics tools, allows deeper investigation of the cross-network relationships between the microbiota and human immune responses. Immune homeostasis is the balance between immunological tolerance and inflammatory immune responses — a key feature in the outcome of health or disease. A healthy microbiota is the qualitative and quantitative ratio of diverse microbes of individual organs and systems, maintaining the biochemical, metabolic and immune equilibrium of the macroorganism necessary to preserve human health. Functional foods, healthy biomicrobiota, healthy lifestyle and controlled protective environmental effects, artificial intelligence and electromagnetic information load/overload are responsible for the work of the human immune system and its ability to respond to pandemic attacks in a timely manner. Obesity continues to be one of the main problems of modern health care due to its high prevalence and polymorbidity. In addition to cardiometabolic diseases, lesions of the musculoskeletal system, obese individuals show impaired cognitive functions, have a high risk of developing depression and anxiety. The gut microbiota mediates between environmental influences (food, lifestyle) and the physiology of the host, and its change may partially explain the cross-link between the above pathologies. It is known that Western eating patterns are the main cause of the obesity epidemic, which also contributes to dysbiotic drift of the gut microbiota, which in turn contributes to the development of complications associated with obesity. Experimental studies in animal models and, to a lesser extent in humans, show that microbiota is associated with obesity and may contribute to the endocrine, neurochemical and development of systemic inflammation underlying obesity itself and related diseases. Nevertheless, a number of questions remain at present. Modeling the microbiota-gut-brain axis, provides the brain with information from the gut not only through the nervous system but also through a continuous stream of microbial, endocrine, metabolic and immune messages. The communication network provides important keys to understanding how obesity and diabetes can affect the brain by provoking neuropsychiatric diseases. The literature review is devoted to the analysis of data on the relationship of the gut-brain axis, obesity and cognitive functions, immune homeostasis and new competencies: psychoneuroimmunology and psychoneuroimmunoendocrinology.
