We conducted an exploratory analysis of plasma and SF samples to define inflammatory profiles, assess plasma-SF correlation and examine longitudinal variations. Using proximity extension assay (PEA), we profiled 92 immune-related proteins in plasma and Sf from 14 oligoJIA patients (untreated or NSAID-treated) and plasma from 28 age and sex-matched healthy controls. Differentially expressed proteins were analysed using gene ontology (GO) and KEGG pathways via STRING. Plasma proteomic immune profiles from oligoJIA patients were highly overlapping with immune profiles of healthy donors. Six proteins were differentially expressed between the two groups. Overall, plasma and SF protein expressions correlated (r = 0.78), mainly driven by 13 proteins including CCL25, FGF21 and KITLG. However, the differentially expressed proteins in plasma did not correlate with those in SF. Longitudinal analysis of 20 SF and 10 plasma samples from one patient revealed immunosuppressive effects of methotrexate (MTX) with distinct kinetics in plasma and SF. Paired SF samples from five patients revealed that cell chemotaxis was a key feature in early disease, distinguishing it from the persistent phase. Immunoprofiling of SF from patients with oligoJIA identified more disease-relevant characteristics than analysis of plasma samples. Several proteins, but not all, correlated between plasma and SF.

Hence, it is urgent to address the question of how SLE can influence female fertility and the impact of hormones on disease manifestation. Mouse models of SLE are suitable tools for studying in detail the interactions of different systems and the impact of lupus development on the process of oogenesis. Lupus-like symptoms were induced through intraperitoneal injection of hydrocarbon oil pristane in healthy Balb/C mice. A short protocol for hormonal stimulation of humans was adapted for mice. Methods used to follow the immune status of the experimental animals were flow cytometry, ELISpot and ELISA, while the variety of autoantibodies, histology and quality of oocytes were characterised using fluorescent microscopy.

HMBPP was recently shown to increase blood meal appetite in malaria mosquitoes. Both IPP and HMBPP are metabolites produced by the normal gut microbiota and apicomplexan parasites such as Plasmodium. To explore potential effects on appetite, male and female mice were treated by gavage with these metabolites, and body mass and gene expression were monitored in brain, stomach and small intestine at 3 h and 7 weeks.

This study investigates sCD40L as a biomarker for disease activity and its utility in stratifying patients for CD40L-targeted therapies. Plasma levels of sCD40L were quantified in SLE patients (n = 169) and healthy controls (n = 100).

K-means clustering grouped patients based on sCD40L concentrations, and principal component analysis (PCA) was performed to assess relationships among disease activity variables. SLE patients exhibited significantly higher sCD40L levels (median 2.2 ng/mL) than healthy controls (median 0.81 ng/mL; p = 0.0079). Elevated sCD40L levels correlated weakly with higher SLE Disease Activity Index (SLEDAI) scores (p = 0.0418), positive Anti-Nuclear Antibody status (p = 0.0133), increased IgG levels (p = 0.0148) and decreased lymphocyte counts (p = 0.0327).
