Immune modulation by melanoma-derived factors

Immune Modulation by Tumor-Derived Extracellular Vesicles in Glioblastoma

Modulation of lung inflammation and immune markers in asthmatic rats treated by Portulaca oleracea

Objective: Previous studies indicated anti-inflammatory effects for Portulaca oleracea in various inflammatory disorders. In this study, the effects of P. oleracea on bronchoalveolar lavage fluid (BALF) levels of total protein (TP), Phospholipase A2(PLA2) and IgE in sensitized rats were examined. Materials and Methods: Male rats were randomly divided into six groups namely, control (group C), s...

Stem Cell-Derived Extracellular Vesicles and Immune-Modulation

Extra-cellular vesicles (EVs) are bilayer membrane structures enriched with proteins, nucleic acids, and other active molecules and have been implicated in many physiological and pathological processes over the past decade. Recently, evidence suggests EVs to play a more dichotomic role in the regulation of the immune system, whereby an immune response may be enhanced or supressed by EVs dependi...

Phenotypic modulation of auto-reactive cells by insertion of tolerogenic molecules via MSC-derived exosomes

Auto-reactive cells-mediated immune responses are responsible for the current tissue damages during autoimmunity. Accordingly, functional modulation of auto-reactive cells has been a pivotal aim in many of recent studies. In the current study, we investigated the possibility for insertion of regulatory molecules onto auto-reactive cells through exosomal nano-shuttles as a novel approach for phe...

Microenvironment-derived factors driving metastatic plasticity in melanoma

Cellular plasticity is a state in which cancer cells exist along a reversible phenotypic spectrum, and underlies key traits such as drug resistance and metastasis. Melanoma plasticity is linked to phenotype switching, where the microenvironment induces switches between invasive/MITFLO versus proliferative/MITFHI states. Since MITF also induces pigmentation, we hypothesize that macrometastatic s...
