Researchers publishing in Aging Cell have discovered how older organisms' susceptibility to pneumonia is related to inflammatory factors. Short-lived infection fighters Polymorphonuclear leukocytes, more commonly known as neutrophils, are part of the first line of defense against lung infections. Illnesses cause these immune cells to be recruited from the bone marrow in a process called...

Epigenetic aging measurements can vary by the time of day at which they are taken, according to a study published in Aging Cell. The circadian rhythm Living on Earth, organisms have evolved to adapt to our planet's day/night cycle. This adaptation is known as the circadian rhythm, and it influences many aspects of biology. As...

A team of researchers has reported in Aging Cell that longer-lived Chinese women have less epigenetic noise in crucial areas of the genome. Order and disorder Epigenetic AlterationsEpigenetic alterations are age-related changes in gene expression that harm the fundamental functions of cells and increase the risk of cancer and other age-related diseases. One of the...

A new review discusses how neutrophils release toxic substances into the body under inflammatory conditions, detailing one of the ways in which chronic inflammation causes long-term damage. Casting a deadly NET As we age, we suffer from the ever-increasing chronic inflammation known as inflammaging. This persistent, smoldering background of low-grade inflammation harms wound healing and...

The potential of the immune system to help repair tissue, including for peripheral nerve damage, Atherosclerosis, and Parkinson’s is considerable. Immune cells not only fight infection; as this new study shows, they also help the nervous system remove debris, paving the way for nerve regeneration following injury. While previous studies suggested that nerve cell damage repair...
