Quantifying activity: a new assay reveals T-cell signalling in tiny skin biopsy samples.

abstract：:Ultra-violet B (UVB)-induced oxidative stress crucially perturbs the epidermal homeostasis, and the skin is endowed with protective mechanisms to take action against such damage. Here, we show the possible involvement of t-SNARE protein syntaxin3, a membrane fusion mediator of cytoplasmic vesicles, and which is releas...
