In previous work, we used the <i>Escherichia coli</i> (<i>E. coli</i>) expression system to biosynthesize a biologically active anti-FGF-2 nanobody (Nb) screened by phage display technology, but the low yield limited its clinical application. In this study, we aimed to increase the yield of anti-FGF-2 Nb, and evaluate its therapeutic potential for psoriasis by inhibiting FGF-2-mediated mitogenic signaling in psoriatic epidermal keratinocytes. We demonstrated a 16-fold improvement in the yield of anti-FGF-2 Nb produced in the <i>Pichia pastoris (P. pastoris)</i> compared to the <i> E. coli</i> expression system. In vitro, the FGF-2-induced HaCaT cell model (FHCM) was established to mimic the key feature of keratinocyte overproliferation in psoriasis. Anti-FGF-2 Nb was able to effectively inhibit the proliferation and migration of FHCM. In vivo, anti-FGF-2 Nb attenuated the severity of imiquimod (IMQ)-induced psoriatic lesions in mice, and also improved the inflammatory microenvironment by inhibiting the secretion of inflammatory cytokines (IL-1β, IL-6, IL-23, and TNF-α), chemokines (CXCL1 and CCL20), and neutrophil infiltration in skin lesions. These were mainly related to the suppression of FGF-2-mediated mitogenic signaling in psoriatic keratinocytes.

The aim of the study was to evaluate the effect of α-LA on lipopolysaccharide (LPS)-induced oxidative stress parameters in rat kidneys. The experimental rats were divided into four groups: I—control (0.9% NaCl i.v.); II—α-LA (60 mg/kg b.w. i.v.); III—LPS (30 mg/kg b.w. i.v.); and IV—LPS + LA (30 mg/kg b.w. i.v. and 60 mg/kg b.w. i.v., respectively).

Structurally, members of the GSDM family possess a C-terminus (an autoinhibitory domain) and a positively charged N-terminus (a pore-forming domain) linked with divergent peptide linkers. Recently, GSDMs have been identified as key executors of pyroptosis (an immunogenic programmed cell death) due to their pore-forming activities on the plasma membrane when proteolytically cleaved by caspases or serine proteases. Accumulating studies suggest that chemoresistance is attributed to dysregulation of apoptotic machinery and that inducing pyroptosis to bypass aberrant apoptosis can potently resensitize apoptosis-resistant cancer to chemotherapeutics. Pyroptosis is initiated by pore formation and culminates with plasma membrane rupture; these processes enable the release of proinflammatory cytokines (e.g., IL-1β and IL-18) and damage-associated molecular patterns, which further modulate antitumor immunity within the tumor microenvironment. Although pyroptosis is considered a promising strategy to boost antitumor effects, it is also reported to cause unwanted tissue damage (e.g., gut damage and nephrotoxicity). Intriguingly, mounting evidence has uncovered nonpyroptotic roles of GSDMs in tumorigenesis, such as proliferation, invasion, metastasis, and drug resistance. Thus, this provides a rationale for GSDMs as potential therapeutic targets. Taken together, we shed unbiased light on the pyroptosis-dependent roles of GSDMs in cancer progression and highlighted how GSDMs modulate tumorigenesis in a pyroptosis-independent manner. It is evident that targeting GSDMs seems profound in cancer management; however, several problems require further investigation to target GSDMs from bench to bedside, which is elucidated in the discussion section.</p></div>","PeriodicalId":8389,"journal":{"name":"Archivum Immunologiae et Therapiae Experimentalis","volume":"71 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9565510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The immunogenicity of both SRM 1648a and LAP-modified OVA was significantly higher than that of control OVA, as measured by the epitope-specific T cell proliferation and interferon γ production by the stimulated cells.

Interestingly, dendritic cells showed enhanced capacity for the uptake of proteins when the cells were cultured with PM-modified OVA. Our results suggest that the enhanced immunogenicity of PM-modified OVA is not associated with altered antigenicity or antigen presentation.
