New study links intestinal protein to food allergy development

When is food simply nourishing and enjoyable, and when does it provoke an allergic reaction? The answer appears to lie in the balance of microbes that live in our intestine – and a specific protein secreted by intestinal goblet cells that influences that balance. Excess amounts of this protein, RELMb, changes the profile of intestinal… Continue reading New study links intestinal protein to food allergy development

Researchers discover how location affects immune cells’ role in fighting disease

The human immune system is like an army of specialized soldiers (immune cells) each with a unique role to play in fighting disease. In a new study published in Nature, led by scientists at the Allen Institute, La Jolla Institute for Immunology, and UC San Diego, researchers reveal how cells known as tissue-resident memory CD8… Continue reading Researchers discover how location affects immune cells’ role in fighting disease

Spatially restricted and ontogenically distinct hepatic macrophages are required for tissue repair

scRNA-seq has uncovered ontogenically distinct hepatic macrophage populations, but their functions remain unclear. Here, De Ponti et al. identify recruited LAMs and resident LAM-like KCs in multiple liver injury models and reveal that TREM2 expression on at least one of these is necessary to clear damaged cells, mediating tissue repair.
