Exposure to the Polychlorinated biphenyl mixture Aroclor 1254 elicits neurological and cardiac developmental effects in early life stage zebrafish (Danio rerio).

The goal of this study was to compare the bioaccumulation of the PCB mixture Aroclor 1254 in zebrafish to cardiac and neurologic outcomes. The establishment of effect concentrations (ECs) for cardiac and neurotoxic effects of PCBs in early life stage fish is challenging due to a lack of measured PCB concentrations in test media (e.g.

Structure of a fully assembled γδ T cell antigen receptor.

T cells in jawed vertebrates comprise two lineages, αβ T cells and γδ T cells, defined by the antigen receptors they express-that is, αβ and γδ T cell receptors (TCRs), respectively. The two lineages have different immunological roles, requiring that γδ TCRs recognize more structurally diverse ligands. Nevertheless, the receptors use shared CD3 subunits to initiate signalling.

Glycoproteomic and proteomic analysis of reveals glycosylation events within FliF and MotB are dispensable for motility.

Unlabelled: Across the Burkholderia genus -linked protein glycosylation is highly conserved. While the inhibition of glycosylation has been shown to be detrimental for virulence in complex species, such as , little is known about how specific glycosylation sites impact protein functionality. Within this study, we sought to improve our understanding of the breadth, dynamics, and requirement for glycosylation across the glycoproteome.
