Objective: To evaluate the frequency of anti-collagen type V in humans with early systemic sclerosis (SSc) compared to defined SSc patients and healthy controls, since collagen type V was shown to be overexpressed in early SSc patients' skin and there is no data concerning the presence of this antibody in early stages of human SSc. Experimental studies showed that animal models immunized with collagen type V developed a disease similar to human systemic sclerosis (SSc), with antibodies production, mainly in early stages post-immunization.
Methods: Eighty-one female SSc patients were included and divided into two groups: early-SSc (18 patients-EULAR Preliminary Criteria) and defined-SSc (63 patients-ACR Criteria 1980). The control group consisted of 19 healthy women age-matched to Early-SSc group. Anti-collagen type V was performed by ELISA. Data was analyzed by appropriate tests.
Results: The prevalence of anti-collagen type V in early-SSc, defined-SSc and control groups was respectively 33, 17 and 5% (p = 0.07). SSc patients with anti-collagen type V had shorter disease duration compared to those without this antibody (8.8 ± 5.1 vs. 14.7 ± 8.9, p = 0.006). Likewise, early-SSc patients with anti-collagen V also had a shorter disease duration than patients negative for this antibody (4.6 ± 2.2 vs. 9.7 ± 5.2, p = 0.04). No association with clinical subsets or scleroderma antibodies specificities was observed (p > 0.05).
Conclusion: The production of anti-collagen type V in SSc seems to be an early event independent of other antibodies specificities. Further studies are necessary to determine if the underlying mechanism for this chronology involves a primary immune response to abnormal expression of collagen type V.

Objective: To assess the expression levels of autoimmune regulator (Aire) and inducible costimulator molecule ligand (ICOSL), as well as T follicular helper (Tfh) cell numbers in rheumatoid arthritis (RA) patients, and to explore their relationship with RA severity. We also aimed to investigate the effect of Aire on arthritis and its underlying mechanisms.
Methods: The expression levels of Aire, ICOSL, and Tfh cell numbers were measured in RA patients.

Osteoarthritis (OA) is a degenerative bone and joint disease characterized by decreased cartilage lubrication, leading to continuous wear and ultimately irreversible damage. This situation is particularly challenging for early-stage OA, as current bio-lubricants lack precise targeting for small inflammatory lesions. In this work, an antibody-mediated targeting hydrogel microspheres (HMS) is developed to precisely lubricate the local injury site of cartilage and prevent the progression of early OA.

Regenerative endodontics aims to restore pulp tissues, thus preserving the vitality of the tooth. One promising approach involves the utilization of decellularized human dental pulp (DHDP) as a scaffold repopulated with Wharton's Jelly mesenchymal stem cells (WJMSCs). This study aimed to regenerate pulp tissues using DHDP and WJMSCs following pulpectomy in mature canine teeth of a feline animal model and to investigate the histological features of the regenerated pulp.

Objective: We aimed to disclose the molecular mechanism of snail1 in liver fibrosis.
Methods: Carbon tetrachloride (CCl) was used to induce a liver fibrosis model in mice whereby serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were evaluated, and liver pathological alternations were assessed. Rat hepatic stellate cells (HSC-T6) were irritated with transforming growth factor (TGF)-β1, followed by assessment of cell viability and migration.
