Bats are a natural reservoir for a wide variety of notorious viruses that are deadly to humans and other mammals but cause no or minimal clinical damage in bats. The co-evolution of bats and viruses for more than sixty million years has established unique and balanced immune defenses within bats against a number of viruses. With the COVID-19 pandemic, bats have gained greater attention as a likely reservoir of the SARS-CoV-2 ancestor virus. The coupling of omics technology and bat research opens an exciting new field to understand and translate discoveries from bats to humans, in the context of infectious disease and beyond. Here, we focus on the mechanism of immunity balance in bats, the application of omics and how this might lead to improvement of human health.

Short-chain fatty acids (SCFAs), primarily acetate (C2), propionate (C3), and butyrate (C4), are crucial microbial metabolites formed by the fermentation of dietary fibers by gut microbiota in the colon. These SCFAs, characterized by fewer than six carbon atoms, serve as an essential energy source for colonic epithelial cells and contribute approximately 10% of the body's total energy requirement. They are central to maintaining gut health through multiple mechanisms, including reinforcing intestinal barrier function, exerting anti-inflammatory effects, regulating glucose and lipid metabolism, and influencing host immune responses.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Obstructive sleep apnea (OSA) is associated with metabolic disorders such as insulin resistance and liver fat accumulation. However, the specific mediating role of liver-related metabolic indicators in this association has not been fully studied. The purpose of this study was to investigate the relationship between Metabolic Score for Insulin Resistance (METS-IR) and OSA, focusing on the mediating effects of liver fat percentage (PLF) and hepatic steatosis index (HSI).

Severe pneumonia remains a major threat to human health, particularly in patients who progress to sepsis, with immune dysregulation playing a central role in its pathophysiological mechanism. Although immunomodulatory therapies have evolved alongside our improved understanding of immune imbalance, conflicting clinical evidence persists. For example, agents targeting similar pathways may produce divergent outcomes, while those with opposing mechanisms of action may yield comparable results.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by widespread inflammation and immune system dysregulation. Recent research suggests that the gut microbiota may play a role in the development of SLE by modulating immune system responses, affecting cytokine production, and altering the activity of T and B cells lymphocytes. As a result, there is a growing interest in microbiota-targeted therapies, including probiotics, dietary changes, and fecal microbiota transplantation.
