Gemcitabine has been used as first-line chemotherapy against lung cancer, but many patients experience cancer recurrence. Activation of anti-tumor immunity in vivo become an important way to prevent Anti-tumor immune responses are often dependent upon the immunogenicity tumors. In our study, we observed that low-dose gemcitabine treatment enhanced by increasing exposure calreticulin, high mobility group box 1 and upregulating expression NKG2D ligands. Further studies demonstrated increased...

Abstract Paraquat is a poisoning herbicide that primarily targets lung, leading to severe acute lung injury characterized by extensive neutrophil infiltration. However, the mechanisms underlying infiltration not clear. In this study, we demonstrated significance of signaling cascade from high-mobility group box 1 (HMGB1), Toll-like receptor 4 (TLR4), interleukin-23 (IL-23), and lastly IL-17A during paraquat-induced subsequent in mice. challenge significantly elevated serum levels IL-23,...

Minocycline, a tetracycline antibiotic, is now known to protect cells via an anti-inflammatory mechanism. We further explored this effect using in vitro model of ischemia-like injury neurons. Coculturing neurons with microglia, the brain's resident immune cell, modestly increased cell death due oxygen and glucose deprivation (OGD), compared alone. Treatment cocultures minocycline decreased level significantly lower than that or inhibitors various mediators, also led death. Importantly,...

The aim of the present study was to investigate therapeutic effect Pulsatilla decoction (PD) on ulcerative colitis (UC) and elucidate its potential molecular mechanisms. C57BL/6 mice expressing natural killer (NK)1.1 were used as experimental animals in a model oxazolone‑induced established. Mice randomly divided into following five groups: i) PD group; ii) iii) IL‑13 intervention iv) 5‑aminosalicylic acid positive control v) negative group (equal volume saline gavage). A total 10 each...

Abstract Antibody repertoire sequencing (Ig-seq) has been widely used in studying humoral responses, with promising results. However, the promise of Ig-seq not yet fully realized, and key features antibody remain elusive or controversial. To clarify these features, we analyzed 2,152 high-quality heavy chain repertoires, representing 582 donors a total 360 million clones. Our study revealed that individuals exhibit very similar gene usage patterns for germline V, D, J genes 53 core V...
