UNIVERSITY OF SOUTH AUSTRALIA Scientists investigating the causes of lymphoedema have made a major discovery, revealing that lymphatic vessels can produce red and white blood cells. Until now, it was believed that blood cells derived solely from stem cells found in bone marrow. The discovery, made by an international team led by University of South...

Role of lymphatic system in bone healing revealed
by University of Oxford Graphical Abstract. Credit: Cell (2023). DOI: 10.1016/j.cell.2022.12.031 It was previously assumed that bones lacked lymphatic vessels, but new research from the MRC Human Immunology Unit at Oxford’s MRC Weatherall Institute for Molecular Medicine not only locates them within bone tissue, but demonstrates their role in bone and blood cell regeneration and reveals changes...

A metabolic enzyme as a potential new target for cancer immune therapies
by German Cancer Research Center The metabolic enzyme IL4I1 (Interleukin-4-Induced-1) promotes the spread of tumor cells and suppresses the immune system. This was discovered by scientists at the German Cancer Research Center (DKFZ) and the Berlin Institute of Health (BIH). The enzyme that activates the dioxin receptor is produced in large quantities by tumor cells....

Newly identified gut cells nurture lymph capillaries
by Institute for Basic Science Fingerlike projections that cover the intestinal wall and absorb nutrients in the small intestine.During digestion, hydrophilic nutrients, such as glucose and amino acids, are absorbed by blood capillaries. On the other hand, hydrophobic nutrients, such as lipids, are taken in by specialized lymphatic capillaries called lacteals. The graphics also shows...

Discovery: Scientists find for the first time how the eyes drain cellular waste and debris
by Delthia Ricks , Medical Xpress Just as the brain is a privileged organ, so too are the eyes. Often poetically called the windows to the soul, a unique set of studies has begun to regard the eyes in another way. Like the brain, the eyes lack the classic lymphatic vessels responsible for the circulation...

Study finds molecule in lymphatic system implicated in autoimmune diseases
HOSPITAL FOR SPECIAL SURGERY (New York City. March 20, 2020.) A study by investigators at Hospital for Special Surgery (HSS) has discovered a molecule in the lymphatic system that has the potential to play a role in autoimmune disease. The study, “Lymph node stromal CCL2 limits antibody responses,” was published online today in the journal...

Exit through the lymphatic system
Our brain swims. It is fully immersed in an aqueous liquid known as cerebrospinal fluid. Every day, the human body produces about half a litre of new cerebrospinal fluid in the cerebral ventricles; this liquid originates from the blood. This same quantity then has to exit the cranial cavity again every day. Researchers in the...
