ABSTRACT Communication is important to ensure the correct and efficient flow of information, which required sustain active social networks. A fine-tuned communication between cells vital maintain homeostasis function multicellular or unicellular organisms in a community environment. Although there are different levels complexity, intercellular communication, prokaryotes mammalians, can occur through secreted molecules (either soluble encapsulated vesicles), tubular structures connecting close channels that link cytoplasm adjacent cells. In mammals, these types serve purposes, may involve distinct factors mediated by extracellular vesicles, tunnelling nanotubes gap junctions. Recent studies have shown connexin 43 (Cx43, also known as GJA1), transmembrane protein initially described junction protein, participates all forms communication; this emphasizes concept adopting strategies maximize potential available resources reutilizing same factor scenarios. Review, we provide an overview most recent advances regarding role Cx43

Exosomes are cell-derived vesicles containing heterogeneous active biomolecules such as proteins, lipids, mRNAs, receptors, immune regulatory molecules, and nucleic acids. They typically range in size from 30 to 150 nm diameter. An exosome's surfaces can be bioengineered with antibodies, fluorescent dye, peptides, tailored for small molecule large biologics. have enormous potential a drug delivery vehicle due enhanced biocompatibility, excellent payload capability, reduced immunogenicity compared alternative polymeric-based carriers. Because of targeting specificity, exosomes capable delivering their cargo exosome-recipient cells. Additionally, potentially act early stage disease diagnostic tools the exosome carries various protein biomarkers associated specific disease. In this review, we summarize recent progress on composition, biological characterization, isolation techniques. Finally, outline clinical applications preclinical advancement provide an outlook importance use targeted delivery, biomarker study, vaccine development.

Gap junctions comprise arrays of intercellular channels formed by connexin proteins and provide for the direct communication between adjacent cells. This type permits coordination cellular activities plays key roles in control cell growth differentiation maintenance tissue homoeostasis. After more than 50 years, deciphering links among connexins, gap cancer, researchers are now beginning to translate this knowledge clinic. The emergence new strategies targeting, combined with an improved understanding molecular bases underlying dysregulation connexins during cancer development, offers novel opportunities clinical applications. However, different isoforms have diverse channel-dependent -independent functions that stage specific. can elicit both pro- anti-tumorigenic effects engender significant challenges path towards personalised medicine. Here, we review current role particular focus on recent progress made determining their prognostic therapeutic potential.

Background ands Aims NAFLD is associated with elevation of many cytokines, particularly IL‐6; however, the role IL‐6 in remains obscure. The aim this study was to examine how myeloid‐specific signaling affects by regulation antifibrotic microRNA‐223 (miR‐223) myeloid cells. Approach and Results Patients or NASH healthy controls were recruited, serum soluble receptor α (sIL‐6Rα) measured. Compared controls, sIL‐6Rα levels elevated NAFLD/NASH patients. correlated positively number circulating leukocytes monocytes. investigated Il6 knockout (KO) A ( Il6ra ) conditional KO mice after high‐fat diet (HFD) feeding.
