A chemokine biomarker for assessing your immune age

A chemokine biomarker for assessing your immune age

Why do some people age faster than others? A recent study has allowed the development of an inflammation index to determine a person’s “immunological age”. This index may be useful in healthcare assessments, and may also allow early-stage interventions, such as improved diet and exercise.

Exosomes in autoimmune disease

Exosomes in autoimmune disease

A pathogenic role of microRNAs (miRNAs) derived from exosomes has been attributed to a growing list of autoimmune conditions. Using exosomes as a biomarker to diagnose autoimmune conditions could help healthcare providers offer effective care prior to irreversible damage.

Biological gradients

Biological gradients

Biological gradients, including ion, oxygen, and protein concentration, are constantly forming and dissipating within cells and tissues. Gradients created by the secretion or metabolism of morphogens enable complex patterning. Without these gradients, cells cease to function and complex organisms would not develop.

Platelet-derived exosomes can help heal ischemic skin wounds

Platelet-derived exosomes can help heal ischemic skin wounds

Inadequate blood supply to the skin can promote the development of wounds. These so-called ischemic wounds affect millions of people and can lead to amputations or even loss of life. Researchers at the Mayo Clinic recently reported their studies in which they examined the use of exosomes containing TGF-β to treat chronic skin wounds.
