Aim Of The Work: To identify the role of serum IL-13, and its receptor subunit expressions as a serologic marker of rheumatoid arthritis (RA)-associated ILD (RA-ILD).
Patients And Methods: Fifty RA patients with ILD and 50 RA patients without ILD were examined, in addition to 50 controls. Disease Activity Score in 28 joints (DAS-28), the Health Assessment Questionnaire (HAQ), and medication history were evaluated. ESR, CRP, RF, Anti-CCP, Serum Krebs von den Lungen-6 (KL-6), surfactant protein D (SP-D) levels, Interleukin 13 and its receptors (IL-13 Rα1 and L-13 Rα2), and mRNA relative expression levels in peripheral blood mononuclear cells (PBMCs) were measured. High-resolution computed tomography (HRCT) scores were used with all RA patients with interstitial lung disease.
Results: Mean age, percent of male affection, duration of the disease, DAS28 and MHAQ were significantly higher in the RA-ILD group than in the RA-no ILD group. ESR, CRP, RF, anti-CCP, serum KL-6, SP-D, IL-13 levels, IL-13 Rα1and IL-13 Rα2 mRNA expressions were significantly increased in RA patients compared to controls; in addition, their levels were significantly higher in the RA-ILD group than in the RA-no ILD group. Serum IL-13 levels and IL-13 Rα1and IL-13 Rα2 were positively correlated with RF, Anti-CCP, KL-6, SP-D, and the HRCT score (P < .001).
Conclusions: Serum IL-13 and its receptor subunit expressions are useful biomarkers which can be used in detecting severity of the interstitial lung disease in RA patients.

Lysosomes are the major cellular organelles responsible for nutrient recycling and degradation of cellular material. Maintenance of lysosomal integrity is essential for cellular homeostasis and lysosomal membrane permeabilization (LMP) sensitizes toward cell death. Damaged lysosomes are repaired or degraded via lysophagy, during which glycans, exposed on ruptured lysosomal membranes, are recognized by galectins leading to K48- and K63-linked poly-ubiquitination (poly-Ub) of lysosomal proteins followed by recruitment of the macroautophagic/autophagic machinery and degradation.

We present a series of three articles on the genetics and pharmacogenetics of G protein- coupled receptors (GPCR). In the first article, we discuss genetic variants of the G protein subunits and accessory proteins that are associated with human phenotypes; in the second article, we build upon this to discuss "G protein-coupled receptor (GPCR) gene variants and human genetic disease" and in the third article, we survey "G protein-coupled receptor pharmacogenomics". In the present article, we review the processes of ligand binding, GPCR activation, inactivation, and receptor trafficking to the membrane in the context of human genetic disease resulting from pathogenic variants of accessory proteins and G proteins.

Objective: To explore the mutation of gene in patients with myelodysplastic syndromes (MDS), and explore their correlation with mutations of other genes, clinical features and prognostic of patients.
Methods: High throughput DNA sequencing was used to identify mutations in common blood tumor genes. The mutational characteristics of the gene and the correlation between gene mutations and patients clinical characteristics and prognosis were retrospectively analyzed.

Interleukin-12 (IL-12) regulates the differentiation of CD4 T lymphocytes into Th1 cells by binding to its receptor, thereby promoting cellular immunity. This study characterized IL-12 and its receptor β2 (IL-12Rβ2) in flounder (Paralichthys olivaceus) and investigated their interaction, effects on T cell proliferation and differentiation, and the adjuvant effects of IL-12. The recombinant IL-12 was successfully expressed, and the IL-12Rβ2 antibody was confirmed to specifically recognize IL-12Rβ2.

A new series of benzo[h]quinoline-containing heterocycles was synthesized via reactions of benzo[h]quinolinyl-2(3H)-furanone with some nitrogen bidentate nucleophiles, leading to the formation of pyridazinone, pyrrolinone, benzimidazole, and benzoxazinone derivatives. The synthesized compounds were evaluated for their insecticidal activity against Culex pipiens L. larvae.
