Basophils articles from across Nature Portfolio

How fibrosis and inflammation are integrated is not entirely clear. Here the authors show that profibrotic proximal tubular cells in the kidneys recruit basophils and activate them to produce interleukin-6 and drive T_H17 cell responses.

Puan and San Luis et al. find that FUT6, encoding a fucosyltransferase, is required for the “rolling” behavior of certain white blood cells that enables them to move from blood vessels to tissues. They show that FUT6 deficiency leads to a loss of the tetrasaccharide sLex on the surface of basophils, resulting in cells that are less sticky and therefore less able to form the necessary adhesions for exiting the blood vessel to drive the allergic reaction.

Eosinophilic esophagitis (EoE) is characterized by esophageal eosinophilia, but the underlying mechanisms promoting eosinophil accumulation remain unclear. David Artis and his colleagues describe a new mouse model of EoE-like disease. The development of EoE-like disease is dependent on thymic stromal lymphopoietin (TSLP) and basophils, whereas inhibition of TSLP or depletion of basophils attenuates established disease. Moreover, individuals with EoE have increased TSLP expression and basophils in the esophagus, suggesting that the TSLP-basophil axis can be targeted in patients with EoE.
