The hypothalamic-pituitary-adrenal (HPA) axis is the main route of immunoregulation, next to (para)sympathetic innervation of organs of the immune system. Immune cells secrete cytokines, which do not only regulate the immune response but also inhibit the actions of other humoral substances at ...
We perform single-cell transcriptomes of 84,363 cells derived from 15 tissue organs of one adult donor and generate an adult human cell atlas. The adult human cell atlas depicts 252 subtypes of cells, including major cell types such as T, B, myeloid, epithelial, and stromal cells, as well...
An increased population of CD4+CD25highFoxp3+ regulatory T cells (Tregs) in the tumor-associated microenvironment plays an important role in cancer immune evasion. However, the underlying mechanism remains unclear. Here we observed an increased secretion

Strong evidences suggest that glutamine (GLN) plays a key role of in several metabolic pathways and it has been recognized as an essential substrate for the appropriate function of many organs and the principal metabolic fuel for different rapidly dividing cells. Moreover, GLN is essential for ...
Researchers worked to determine the biological age (how fast something is ageing) of nine organs (heart, blood vessels, liver, immune system, pancreas, kidneys, lungs, intestines, and the brain) and for the entire body. They measured the gap between a person’s chronological (actual...
