Cytokines such as TNF-α have a validated role in the immunopathogensis of ulcerative colitis (UC), and intercepting inflammatory cytokines is currently the best option for maximizing treatment efficacy. One of the major sources of inflammatory cytokines are myeloid linage leucocytes (granulocytes, monocytes), which are present in great numbers in the colonic tissue. Their selective depletion by adsorptive granulocyte, monocyte apheresis (GMA), should be therapeutic in patients with UC, although until now efficacy outcomes have been both encouraging and disappointing. The authors' view is that in patients with UC, there is an evolving scope for therapeutic opportunity based on taking away the sources of inflammatory cytokines, also considering the favorable safety profile of GMA.

Background: Chronic inflammation is well recognized as a key factor related to renal function deterioration in patients with diabetic kidney disease (DKD). Neutrophil extracellular traps (NETs) play an important role in amplifying inflammation. With respect to NET-related genes, the aim of this study was to explore the mechanism of DKD progression and therefore identify potential intervention targets.

IL-27 is structurally an immune-enhancing and pleiotropic two-chain cytokine associated with IL-12 and IL-6 families. IL-27 contains two subunits, namely IL-27p28 and EBI3. A heterodimer receptor of IL-27, composed of IL27Rα (WSX1) and IL6ST (gp130) chains, mediates the IL-27 function following the activation of STAT1 and STAT3 signaling pathways.

NIM-1324 is an oral investigational new drug for autoimmune disease that targets the Lanthionine Synthetase C-like 2 (LANCL2) pathway. Through activation of LANCL2, NIM-1324 modulates CD4+ T cells to bias signaling and cellular metabolism toward increased immunoregulatory function while providing similar support to phagocytes. In primary human immune cells, NIM-1324 reduces type I interferon and inflammatory cytokine (IL-6, IL-8) production.

Autoreactive antibodies (AAB) are currently being investigated as causative or aggravating factors during post-COVID. In this study we analyze the effect of immunoadsorption therapy on symptom improvement and the relationship with immunological parameters in post-COVID patients exhibiting symptoms of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) induced or aggravated by an SARS-CoV-2 infection. This observational study includes 12 post-COVID patients exhibiting a predominance of ME/CFS symptoms alongside increased concentrations of autonomic nervous system receptors (ANSR) autoantibodies and neurological impairments.

Biotics are increasingly being used in the treatment of irritable bowel syndrome (IBS). This study aimed to assess the efficacy and safety of a mixture of microencapsulated sodium butyrate, probiotics ( DSM 26357, DSM 32418, DSM 32946, DSM 32403, and DSM 32269), and short-chain fructooligosaccharides (scFOSs) in IBS patients. This was a randomized, double-blind, placebo-controlled trial involving 120 adult participants with IBS.
