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

Immunologic difference between hypersensitivity to mosquito bite and hemophagocytic lymphohistiocytosis associated with Epstein-Barr virus infection. [PDF]
PLoS ONE, 2013 Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening, virus-triggered immune disease. Hypersensitivity to mosquito bite (HMB), a presentation of Chronic Active Epstein-Barr Virus infection (CAEBV), may progress to HLH.

Stochastic model of T Cell repolarization during target elimination (II) [PDF]
, 2021 Cytotoxic T lymphocytes (T cells) and natural killer cells form a tight contact, the immunological synapse (IS), with target cells, where they release their lytic granules containing perforin/granzyme and cytokine containing vesicles. During this process the cell repolarizes and moves the microtubule organizing center (MTOC) towards the IS.

An Inhibitory Role for Human CD96 Endodomain in T Cell Anti-Tumor Responses
Cells, 2023 Immune checkpoint blockade (ICB) therapy involves the inhibition of immune checkpoint regulators which reverses their limitation of T cell anti-tumor responses and results in long-lasting tumor regression. However, poor clinical response or tumor relapse

Cytotoxic and Immunologic Effects of Methotrexate in Psoriasis
Journal of Investigative Dermatology, 1990 Based on recent experience that Cyclosporin A, an immunosuppressive drug, produces marked improvement in psoriasis, possible immunomodulatory activities of methotrexate (MTX) have been reviewed to look for alternate mechanisms of MTX action in psoriasis. It is generally considered that the therapeutic results of MTX in psoriasis are related to a direct

In vitro bio-immunological and cytotoxicity studies of poly(2-oxazolines) [PDF]
Journal of Materials Science: Materials in Medicine, 2011 Poly(2-oxazolines) with varying alkyl chain lengths (e.g., methyl, ethyl, aryl) and molar masses have been tested for cell cytotoxicity in vitro. A standard 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used for the estimation of cell viability.
