An indirect phenotyping method was developed in order to estimate the susceptibility of rubber tree clonal varieties to Corynespora Leaf Fall (CLF) disease caused by the ascomycete Corynespora cassiicola. This method consists in quantifying the impact of fungal exudates on detached leaves by measuring the induced electrolyte leakage (EL%). The tested exudates were either crude culture filtrates from diverse C. cassiicola isolates or the purified cassiicolin (Cas1), a small secreted effector protein produced by the aggressive isolate CCP...

Bone and cartilage destruction is one of the key manifestations of rheumatoid arthritis (RA). Although the role of T helper (Th)17 cells in these processes is clear, the role of IL-21-producing cells T cells has been neglected. We sought to investigate the role of IL-21 in RA by focusing on the functional characteristics of the main producers of this cytokine, synovial CD4(+)IL-21(+) T cells. We show that the frequency of both synovial fluid (SF) CD4(+)IL-21(+) or CD4(+)IL-21(+)TNF(+) T cells in patients with RA was significantly higher compared with patients with psoriatic arthritis (PsA)...

OBJECTIVE: The molecular mechanism of citrullination involves the calcium-dependent peptidylarginine deiminase (PAD) family of enzymes. These enzymes induce a stereochemical modification of normal proteins and transform them into autoantigens, which in rheumatoid arthritis trigger a complex cascade of joint inflammatory events followed by chronic synovitis, pannus formation, and finally, cartilage destruction. By hypothesizing that PAD2 and PAD4 enzymes produce autoantigens, we investigated five possible synovial protein targets of PAD enzymes...

Supramolecular approach plays pivotal role in the construction of smart and functional materials due to the reversible nature of noncovalent interactions. In the present work, two compounds, cholesterol-functionalized calix[4]pyrrole (CCP) and perylene bisimide diacid (PDA), were synthesized. Little fluorescence is observed in the ethanol solution of the mixture of CCP and PDA, while the solution turns fluorescent upon introduction of ammonia, which is attributed to the formation of a supramolecular ensemble, PDA/(CCP)2/NH3...

BACKGROUND: Anti-cyclic citrullinated peptides (CCPs) are autoantibodies directed against citrullinated peptides. Rheumatoid factor (RF), an antibody against the Fc portion of IgG, is known to form immune complexes and contribute to the etiopathogenesis of various skin disorders. C-reactive protein (CRP), an acute-phase protein, increases following secretion of interleukin-6 from macrophages and T cells. Anti-CCP, RF, and CRP are well-established immune-markers, their diagnostic potential in immune-mediated skin disorders remains less widely studied...

Autoimmune diseases are considered the 3rd leading cause of morbidity and mortality in the industrialized countries. Autoimmune thyroid diseases (ATDs) are associated with high prevalence of nonorgan-specific autoantibodies, such as antinuclear antibodies (ANA), antidouble-stranded deoxyribonucleic acid (anti-dsDNA), antiextractable-nuclear antigens (anti-ENAs), rheumatoid factor (RF), and anticyclic-citrullinated peptides (anti-CCP) whose clinical significance is unknown.We aimed to assess the prevalence of various nonorgan-specific autoantibodies in patients with ATD, and to investigate the possible association between these autoantibodies and occurrence of rheumatic diseases and, if these autoantibodies could be considered as predictor markers for autoimmune rheumatic diseases in the future...

A boy presented initially to a Rheumatology clinic with a three year history of asymptomatic swelling of the third to fourth proximal interphalangeal (PIP) joints bilaterally. A presumptive diagnosis of seronegative arthritis was made. Sulfasalazine was commenced without improvement and resulted in mood disturbance. Blood tests including ESR, lupus anticoagulant, rheumatoid factor and CCP antibodies were unremarkable. Hand radiographs were normal. MRI showed oedema within soft tissues around PIP joints. His care was transferred to the Rheumatology unit in our hospital and the rheumatological diagnosis was revised; sulfasalazine was stopped and skin biopsy organised...
