Abstract
AIM Although F11 receptor (F11R), also named junctional adhesion molecular A (JAM-A), participates in leukocyte migration, its role in autoimmune diseases has not been specifically disclosed. In this study, we examined the association of F11R expression with the development and clinical manifestations of rheumatoid arthritis (RA). METHOD RNA from peripheral blood mononuclear cells (PBMCs) and DNA from the peripheral blood in RA patients and a healthy control group were extracted. F11R messenger RNA (mRNA) expression was determined by quantitative real-time polymerase chain reaction. The F11R polymorphisms were determined by the TaqMan genotyping assay. RESULTS There was more F11R mRNA expression in the PBMCs of RA patients than those of the control group (P = 0.018). In F11R promoter -688 A > C, C carriers have lower titers of the anticyclic citrullinated peptide (anti-CCP) antibodies (P = 0.002) and fewer positive rates of Schirmer's tests (P = 0.009). The effect is independent of the existence of HLA-DR4. Different genotypes in F11R promoter -688 A > C and -436 A > G do not lead to changes of the gene expression in RA patients. CONCLUSION RA patients have higher mRNA expression of F11R. In RA patients, F11R -688 C may be a protective factor for the development of anti-CCP antibodies and positive rates of Schirmer's tests.

Abstract
Far from being merely a passive cholesterol accumulation within the arterial wall, the development of atherosclerosis is currently known to imply both inflammation and immune effector mechanisms. Adaptive immunity has been implicated in the process of disease initiation and progression interwined with traditional cardiovascular risk factors. Although the body of knowledge regarding the correlation between atherosclerosis and immunity in humans is growing rapidly, a relevant proportion of it derives from studies carried out in animal models of cardiovascular disease (CVD). However, while the mouse is a well-suited model, the results obtained therein are not fully transferrable to the human setting due to intrinsic genomic and environmental differences. In the present review, we will discuss mainly human findings, obtained either by examination of post-mortem and surgical atherosclerotic material or through the analysis of the immunological profile of peripheral blood cells. In particular, we will discuss the findings supporting a pro-atherogenic role of T cell subsets, such as effector memory T cells or the potential protective function of regulatory T cells. Recent studies suggest that traditional T cell-driven B2 cell responses appear to be atherogenic, while innate B1 cells appear to exert a protective action through the secretion of naturally occurring antibodies. The insights into the immune pathogenesis of atherosclerosis can provide new targets in the quest for novel therapeutic targets to abate CVD morbidity and mortality.

Abstract
A serum metabolomics method based on rapid resolution liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (RRLC-Q-TOF-MS) was performed for a holistic evaluation of the metabolic changes of collagen-induced arthritis (CIA) in rats and to assess the interventional effects of type II collagen (CII) in this model. Partial least-squares-discriminant analysis (PLS-DA) was employed to study the metabolic profiling of CIA rats and control rats. Ten metabolites, namely, 12(S)-HHTrE, 12(S)-HEPE, PGE2, TXB2, 12(S)-HETE, LysoPE(16:0), PE(O-18:0/0:0), Lyso-PE(18:2), Lyso-PE(20:4), and Lyso-PC(22:5) were identified as differential metabolites associated with the pathogenesis of CIA. These results suggested that dysregulation of the arachidonic acid (AA) and phospholipid metabolic networks is involved in the pathomechanism of CIA. Differential metabolomics and histopathological analyses demonstrated that CII inhibits the progress of arthritis. Furthermore, the therapeutic effects of CII on CIA may involve regulation of the disordered AA and phospholipid metabolic networks. This metabolomics study provides new insights into the pathogenesis of arthritis and, furthermore, indicates the potential mechanism underlying the significantly increased prevalence of metabolic syndrome, defined as a clustering of cardiovascular disease (CVD) risk factors, in arthritis patients.
