: an emerging One Health pathogen.

Unlabelled: is an opportunistic human and animal pathogen severely understudied. Here, we conducted the largest genomic epidemiological study on this pathogen to date. Our data show that this bacterium has spread globally.

Brucella abortus induces mast cell activation through TLR-2 and TLR-4.

The Gram-negative bacteria Brucella abortus is a major cause of brucellosis in animals and humans. The host innate immune response to B. abortus is mainly associated with phagocytic cells such as dendritic cells, neutrophils, and macrophages.

Intermediate snowpack melt-out dates guarantee the highest seasonal grasslands greening in the Pyrenees.

In mountain areas, the phenology and productivity of grassland are closely related to snow dynamics. However, the influence that snow melt timing has on grassland growing still needs further attention for a full understanding, particularly at high spatial resolution. Aiming to reduce this knowledge gap, this work exploits 1 m resolution snow depth and Normalized Difference Vegetation Index observations acquired with an Unmanned Aerial Vehicle at a sub-alpine site in the Pyrenees.

Valproic acid restricts mast cell activation by Listeria monocytogenes.

Mast cells (MC) play a central role in the early containment of bacterial infections, such as that caused by Listeria monocytogenes (L.m). The mechanisms of MC activation induced by L.

TLR2 Regulates Mast Cell IL-6 and IL-13 Production During Infection.

(L.m) is efficiently controlled by several cells of the innate immunity, including the Mast Cell (MC). MC is activated by L.
