Rabbit Anti-Human HSP60 polyclonal antibody

Exosomes have been intensively studied in autoimmune diseases, and circulating exosomes and microvesicles have also been explored in autoimmune thyroiditis (AITD). However, the role of thyroid cell-derived exosomes in immune responses is unclear. We showed that IFN-gamma-treated Nthy-ori 3-1 cell-derived exosomes (IFN-gamma-Exo) harbored TPO, HSP60 and MHC-II and activated dendritic cells (DCs) in vitro. Compared with Exo-targeted DCs (DCExo), IFN-gamma-Exo-targeted DCs (DCIFN-gamma-Exo) promoted the expression and release of proinflammatory cytokines, such as IFN-gamma, IL-17A and IL-22, from CD4(+) T lymphocytes and inhibited the expression and release of antiinflammatory cytokines, such as IL-4, IL-10 and TGF-beta 1; however, IFN-gamma-Exo did not have this effect compared with Nthy-ori 3-1 cell-derived exosomes (Exo). DCIFN-gamma-Exo stimulates the expression and release of cytokines from CD4(+) T lymphocytes more efficiently than FN-gamma-Exo. Thus, DC(IFN-gamma-Exo )may effectively induce CD4(+) T lymphocyte-mediated immune responses and play a role in the occurrence and development of AITD.

Genus Botrytis contains approximately 35 species, many of which are economically-important and globally-distributed plant pathogens which collectively infect over 1,400 plant species. Recent efforts to genetically characterize genus Botrytis have revealed new species on diverse host crops around the world. In this study, surveys and subsequent genetic analysis of the glyceraldehyde-3-phosate dehydrogenase (G3PDH), heat-shock protein 60 (HSP60), DNA-dependent RNA polymerase subunit II (RPB2), and necrosis and ethylene-inducing proteins 1 and 2 (NEP1 and NEP2) genes indicated that Botrytis isolates collected from peony fields in the United States contained more species diversity than ever before reported on a single host, including up to 10 potentially novel species. Together, up to 16 different phylogenetic species were found in association with peonies in the Pacific Northwest, which is over a third of the total number of species that are currently named. Furthermore, species were found on peonies in Alaska that have been described on other host plants in different parts of the world, indicating a wider geographic and host distribution than previously thought. Lastly, some isolates found on peony share sequence similarity with unnamed species found living as endophytes in weedy hosts, suggesting that the isolates found on peony have flexible lifestyles as recently discovered in the genus. Selected pathogenicity, growth, and morphological characteristics of the putatively new Botrytis species were also assessed to provide a basis for future formal description of the isolates as new species.
