Performance evaluation of the LIOFeron®TB/LTBI IGRA for screening of paediatric LTBI and tuberculosis.

Purpose: High-accuracy diagnostic screening tests for Mycobacterium tuberculosis (MTB) infection are required, primarily to detect patients with latent infections (LTBIs) in order to avoid their progression to active tuberculosis disease. The performance of the novel IGRA LIOFeron®TB/LTBI was evaluated in children. The originality of this test is the new MTB antigen contained (L-alanine dehydrogenase), identified as a tool to differentiate active TB from LTBI infection.

The present study aimed to assess the capability of biomarkers, including inflammatory indicators, anaemic markers, lipid markers, and renal function indices, to differentiate between different stages of chronic kidney disease (CKD). Expected to provide a new strategy for monitoring the development of CKD and stratified treatment management, providing valuable insights for future biomarker studies to explore early detection of CKD. The changes in inflammatory markers (interferon gamma [IFN-γ], interleukin [IL]-17A, IL-10, IL-6, IL-4, IL-2, IL-1 and white blood cells [WBC]), lipid markers (high-density lipoprotein cholesterol [HDL-c], low-density lipoprotein cholesterol [LDL-c], and triglyceride [TG]), indicators of kidney injury (serum creatinine [Scr] and blood urea nitrogen [BUN]) in 451 patients with different stages of CKD were examined.

The Janus kinase/signal transducer and activator of transfection (JAK/STAT) system is comprised of multiple cell surface receptors, receptor tyrosine kinases, and signal transducers that are key components of numerous systems involved in malignancy, inflammation, immune surveillance and development, cellular proliferation, metabolism, differentiation, apoptosis, and hematologic disorders, all of which when disrupted can produce severe disease. Nevertheless, small molecule inhibitors of the four known JAKs, termed JAKinibs, have found therapeutic indications for a broad category of diseases. In this perspective, I will summarize the development of JAK inhibitors, whose origins were in antiquity, with particular attention to their use in treating patients with inflammatory bowel disease (IBD).

Melanoma differentiation-associated gene 5 (MDA5) initiates type I interferon (IFN) production by detecting cytosolic viral RNA. Mammalian MDA5 is an IFN-inducible gene and controlled by IFN regulatory factor 1 (IRF1). Teleost MDA5 also induces type I IFN production in response to viruses, yet its regulation remains largely unexplored.

IKKε is a traditional antiviral kinase known for positively regulating the production of type I interferon (IFN) and the expression of IFN-stimulated genes (ISGs) during various virus infections. However, through an inhibitor screen targeting cellular kinases, we found that IKKε plays a crucial role in the lytic replication of Kaposi's sarcoma-associated herpesvirus (KSHV). Mechanistically, during KSHV lytic replication, IKKε undergoes significant SUMOylation at both Lys321 and Lys549 by the viral SUMO E3 ligase ORF45.
