Mast Cells and Arteriogenesis: A Systematic Review.

Vascular occlusive diseases remain a major health burden worldwide, necessitating a deeper understanding of the adaptive responses that mitigate their impact. Arteriogenesis, the growth and remodeling of collateral vessels in response to arterial occlusion, is a vital defense mechanism that counteracts fluid shear stress-induced vascular stenosis or occlusion. While physical factors driving arteriogenesis have been extensively studied, the specific cellular mediators involved are poorly understood.

Antioxidant and membrane-protective effects of the 3-O-ethyl ascorbic acid-cannabigerol system on UVB-irradiated human keratinocytes.

The lack of effective protection against UVB radiation, that severely disrupts the metabolism of keratinocytes, underlines the search for bioactive compounds that would provide effective protection without causing side effects. Therefore, the aim of the study has been to assess the effect of two compounds, that are different in terms of structure and properties: 3-O-ethyl ascorbic acid-EAA (a stable derivative of vitamin C) and cannabigerol-CBG, used separately or concurrently, on the metabolism of keratinocytes previously exposed to UVB. The obtained results indicate diverse, yet mutually reinforcing localization of the tested compounds, both within the membrane structures and cytosol.
