By using a variety of molecular techniques, we have characterized the cytokine profile of pro-T cells. During this characterization we cloned a novel cytokine that has chemotactic activities. We have designated this cytokine lymphotactin. The structural analysis, chromosomal location, and biological properties of lymphotactin provide strong evidence that this cytokine represents a new class of chemokine.

In cutaneous melanoma, epigenetic dysregulation is implicated in drug resistance and tumor immune escape. However, the epigenetic mechanisms that influence immune escape remain poorly understood. To elucidate how epigenetic dysregulation alters the expression of surface proteins that may be involved in drug targeting and immune escape, we performed a 3-dimensional surfaceome screen in primary melanoma cultures and identified the DNA-methyltransferase inhibitor decitabine as significantly upregulating the costimulatory molecule ICAM-1.

is a perennial medicinal herb with important immunomodulatory and anti-inflammatory properties, especially purported for the alleviation of cold and flu symptoms. Different classes of secondary metabolites of the plant, such as alkylamides, caffeic acid derivatives, polysaccharides, flavonoids, and glycoproteins, are believed to be biologically and pharmacologically active. Although previous research suggests that the alkylamides present in may be responsible for reducing the symptoms associated with the common cold or flu through their immunomodulatory activity, the roles of specific alkylamides and their targets (i.

The antiretroviral therapy program's success in managing the human immunodeficiency virus (HIV) has inadvertently led to the release of antiretrovirals (ARVs) into worldwide aquatic ecosystems. However, few studies investigated the risks of ARV loadings that flow continuously to the marine waters of South America (such as Brazil). Against this backdrop, the aims of this study were: (i) to estimate the Predicted Environmental Concentration (PEC) of thirteen ARVs worldwide used in HIV treatment, and which are frequently disposed of in the marine aquatic ecosystems of Guarujá, São Paulo coastline, Brazil.

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by severe liver inflammation and fibrosis due to an imbalanced immune response caused by enhanced bacterial components. The progression of MASH is closely linked to increased permeability of intestinal mucosal barrier facilitating enter of bacterial components into hepatic portal venous system. B cells are important immune cells for adaptive responses and enhance hepatic inflammation through cytokine production and T cell activation.

The global increase in cancer cases and mortality has been associated with inflammatory processes, in which chemokines play crucial roles. These molecules, a subfamily of cytokines, are essential for the migration, adhesion, interaction, and positioning of immune cells throughout the body. Chemokines primarily originate in response to pathogenic stimuli and inflammatory cytokines.
