UV Photoprotection, Cytotoxicity and Immunology Capacity of Red Algae Extracts [PDF]

open access: yesMolecules, 2019
This study was designed to evaluate the potential use of algal extracts in cosmeceuticals, including factors related to biosecurity. The aqueous crude extracts of Hydropuntia cornea and Gracilariopsis longissima showed a good photoprotective capacity (Sun Protection Factor, SPF) due to, among other reasons, the presence of five types of mycosporine ...

Lung tumor microenvironment induces specific gene expression signature in intratumoral NK cells

open access: yesFrontiers in Immunology, 2013
Natural Killer (NK) cells are able to recognize and kill tumor cells, however whether they contribute to tumor immunosurveillance is still debated. Our previous studies demonstrated the presence of NK cells in human lung tumors.
