Summary Thymic stromal lymphopoietin (TSLP) has been suggested recently to play an important role in the pathophysiology of rheumatoid arthritis (RA). However, there is little information on serum TSLP concentrations in RA and its clinical significance. The present study investigated whether serum TSLP concentrations were affected in patients with RA. Using an enzyme‐linked immunosorbent assay (ELISA), we measured TSLP concentrations in the serum obtained from 100 patients with RA, 60 patients with osteoarthritis (OA) and 34 healthy volunteers. We also investigated the correlation between serum TSLP concentrations and clinical parameters of disease activity in RA [disease activity score using 28 joint counts (DAS28)‐C‐reactive protein (CRP), DAS28‐erythrocyte sedimentation rate (ESR), Clinical Disease Activity Index (CDAI]), patient's/‐physician's Visual Analogue Scale (VAS), swollen joints count, tender joints count, CRP, ESR and matrix metalloproteinase‐3 (MMP‐3) concentrations]. In addition, we investigated the correlation between serum TSLP concentrations and anti‐citrullinated peptide antibody (ACPA) and serum tumour necrosis factor (TNF)‐α. Serum TSLP levels in patients with RA were significantly higher than those in patients with OA and in healthy volunteers. Interestingly, serum TSLP concentrations were correlated significantly with ACPA titres, but not with other clinical parameters. There was a significant increase in serum TSLP concentrations in patients with RA, which was correlated positively with serum ACPA titres. These findings suggest that in patients with RA, TSLP may play a role in ACPA production by B cells.

Ligand–receptor dissociated expression explains high TSLP without prognostic impact in human primary head and neck squamous cell carcinoma

Thymic stromal lymphopoietin (TSLP) is an interleukin (IL)-7-like cytokine expressed by epithelial cells during allergic inflammation, and activating dendritic cells (DC). Its expression and functional role in cancer remain controversial. We conducted retrospective (n D 89), and prospective studies including patients with untreated primary head and neck squamous cell carcinoma (HNSCC). We found that TSLP was overexpressed by HNSCC tumor cells, and associated with a highly differentiated status. However, no significant difference in overall and recurrence-free survival was found between patients bearing a tumor with high and low TSLP levels, respectively. Surprisingly, there was no significant association between the levels of TSLP expression, and the number of tumor-infiltrating mature DCLAMP C DC. In order to explain the apparent lack of TSLP-induced DC activation, we performed phenotypic and functional experiments on freshly resected tumors. Tumor-infiltrating immune cells, including DC, did not express the TSLP receptor heterodimer (TSLPR chain, IL-7Ralpha chain). Furthermore, freshly sorted blood CD11c C DC from healthy donors cultured with tumor-conditioned supernatant exhibited an activated profile, but this was not affected by an anti-TSLP blocking antibody, suggesting a DC activation pathway independent of tumor-derived TSLP. Overall, our results demonstrate that TSLP is overexpressed in HNSCC but its function is hampered by the lack of TSLPR-expressing cells in the tumor microenvironment. Such a dissociated ligand-receptor expression may impact intercellular communication in other immune activation pathways, and tumor types.Abbreviations: DC, dendritic cells; HNSCC, head and neck squamous cell carcinoma; TSLP, thymic stromal lymphopoeitin KEYWORDS Cytokines; dendritic cells; head and neck squamous cell carcinoma; thymic stromal lymphopoietin; tumor microenvironment

“…When LPS receptors or CD14 on these cells are activated, inflammation is triggered by the NF-κB pathway. As results of LPS induction, the activated immune cells immediately secrete TNF-α as well as other pro-inflammatory cytokine which probably lead to IL17, IL24, and IL33 production from keratinocytes (Balato et al, 2012;Chiricozzi et al, 2011;Kumari et al, 2013;Volpe et al, 2014). Furthermore, mutations in loci coding the transcriptional factors may initiate lesions.…”

Introduction: Guttate is a type of psoriasis in which patients are sensitive to Streptococcus pneumoniae throughout innate immune responses. During the inflammation, tumour necrosis factor alpha (TNF-α), a well-known pro-inflammatory cytokine, is expressed; meanwhile interleukin 10 (IL-10) and heparin-binding EGF-like growth factor (HB-EGF), which are capable of inhibiting transcription of the TNF-α gene, are also prominent. Furthermore, HB-EGF only impacts fibroblasts and keratinocytes which promote psoriatic lesions. In this study, we looked for differences of TNF-α, IL-10 and HB-EGF expression between a psoriatic patient and a non-psoriatic relative. Methods: To achieve our target, peripheral blood mononuclear cells (PBMCs) expressing LPS receptors or CD14 (CD14+ cells) derived from a guttate patient, and the donor's father (without psoriatic symptoms), were activated for 7 days by a lysate of Streptococcus pneumoniae for 24 hours before being harvested. Results: Results showed detectable mRNAs of TNF-α, IL-10 and HB-EGF from isolated CD14+ cells of guttate patient were more intensive expression than the non-psoriatic one at 24 hours after engaging the bacterial components. In addition, transcription of HB-EGF gene from the guttate patient was maintained over 168 hours, while its mRNA level from the nonpsoriatic volunteer was only expressed within 24 hours. Conclusion: Finally, in initial results of inflammatory effects between strains, the Streptococcal lysate was seen to have stronger immune responses than the Staphylococcal lysate on the immune cells of the guttate psoriasis.
