Summary: This study has developed a novel dual-specificity inhibitor that can simultaneously target SARS-CoV-2 infection and virus-induced hyperinflammation. By fusing an inhibitor of viral cell entry with a molecule blocking IL-6, this molecule may have the potential to efficiently ameliorate symptoms of COVID-19 in infected individuals.

Summary: The combination of IL-6 and sIL-6R enhances the formation and bone resorption of osteoclasts induced by low levels of RANKL. Blocking sIL-6R can inhibit NF-kappa B and JNK signaling pathways to eliminate this promotive effect.

Summary: This study investigated the involvement of IL-6 trans-signaling in DVT and found a strong correlation between the Asp358Ala variant and sIL6-R levels. The high frequency of the Asp358Ala mutation and elevated IL-6 levels in DVT patients may explain the association between IL-6 overactivation and DVT outcome. These findings provide a proof of concept for targeting IL-6 trans-signaling as a new strategy for DVT adjuvant therapy.

Summary: This review discusses the discovery of the IL-6 trans-signalling pathway and the development of biologics that specifically inhibit this pathway. Targeting IL-6 trans-signalling can decrease disease-promoting activities of IL-6 without blocking its protective actions.

Summary: IL-6 is a cytokine involved in immunity, neural cell maintenance, and metabolism. It is synthesized by various cells and its levels are elevated during infection and inflammation. IL-6 binds to a receptor complex and can also act on cells without the IL-6 receptor through trans-signaling.

Summary: CypA positively regulates the IL-6 trans-signaling pathway by inhibiting degradation of IL-6 membrane receptor gp130 and enhancing its dimerization, while its expression is negatively regulated by SOCS1. SOCS1 interacts with CypA and promotes its degradation through ubiquitination, thus inhibiting the IL-6 trans-signaling pathway.

Summary: Interleukin (IL)-6 is an emerging therapeutic target in myocardial infarction (MI), with the novel recombinant fusion protein sgp130Fc showing efficacy in exclusive trans-signaling blockade. In a rat model, sgp130Fc attenuated infiltration and preserved cardiac function, in contrast to anti-IL-6 antibodies that result in panantagonism.

Summary: CAR-T cell therapies have shown high clinical response rates in B cell malignancies, with potential for solid tumor treatment. Modulating IL-6 trans-signaling through GP130/STAT3 pathway enhances CAR-T cell expansion and antitumor activity, while GP130 expression in CAR-T cells improves antitumor efficacy without systemic IL-6 trans-signaling, indicating the potential for therapeutic applications.

Summary: A library of glycoforms of human interleukin 6 (IL-6) was generated using semisynthesis, and their in vivo plasma clearance rates in rats were evaluated. The results showed that IL-6 glycoforms with different structures exhibited varying clearance rates in the body, with 2,6-sialylated glycoforms of IL-6 being cleared faster in most cases.

Summary: This study provides insights into the structure and function of the conserved iRhom homology domain (IRHD) and identifies a key motif within IRHD that affects the transport and stability of the iRhom-ADAM17 complex. Mutation of this motif hinders the secretion pathway and prolongs the half-life of iRhom2 and ADAM17. Additionally, disruption of this motif alters the interaction profile of iRhom2 with proteins involved in intracellular vesicle transport.

Summary: The study reveals that perturbation of the actin cytoskeleton is not sufficient to induce NF-kappa B activation and IL-6 secretion, but it reduces IL-6-induced activation of STAT3 in Hep3B cells. Additionally, IL-6 receptor proteolysis by ADAM10 is not dependent on the integrity of the actin cytoskeleton.

Summary: Plant-produced antibodies showed promising results as passive immunoprophylaxis in a breastfeeding model in newborns. The use of human neutralizing antibodies effectively prevented infection in newborn monkeys and offered advantages in cost of production and safety. The findings suggest that anti-Env antibodies may play a role in controlling viral replication in this newborn model.

Summary: IL-11, a member of the IL-6 family of cytokines, was originally discovered as a factor that promotes megakaryocyte maturation, but recent research has revealed its crucial roles in inflammation, fibrosis, and cancer. IL-11 initiates signaling through both classic and trans-signaling mechanisms, impacting the activation of cells that do not express the IL-11 receptor.

Summary: Interleukin-6 (IL-6) is a pleiotropic cytokine involved in various physiological and pathophysiological functions. It can signal through different pathways, with trans-signaling playing a crucial role in its pro-inflammatory properties. The soluble form of the IL-6 receptor (sIL-6R) is generated by different mechanisms, including proteolysis. Attempts to selectively block IL-6 trans-signaling are being made in pre-clinical animal models and clinical studies for inflammatory bowel disease.

Summary: This study shows that ADAM10 is an important shedding protease for ACE2, and ACE2 can also be released in extracellular vesicles. The degree of ACE2 shedding mediated by ADAM10 and ADAM17 depends on stimulatory conditions and the expression level of the ADAM17 regulator iRhom2.

Summary: The cytokine IL-2 plays a crucial role in immune homeostasis. This study demonstrates that metalloproteases ADAM10 and ADAM17 can cleave the IL-2R alpha, generating a soluble ectodomain that inhibits IL-2 signaling in T cells. Manipulating the cleavage of IL-2R alpha offers a potential opportunity to alter IL-2 function.

Summary: Inflammation plays an important role in atherosclerotic cardiovascular disease, and there is a need for therapies targeting excessive inflammation. A fusion protein called olamkicept has been shown to reduce atherosclerosis independently of LDL cholesterol metabolism in mice, and its use in a patient with high-risk ASCVD also demonstrated a reduction in arterial wall inflammation.

Summary: This study analyzed two variants of the interleukin-11 receptor (IL-11R) found in patients with craniosynostosis. The results showed that the IL-11R-E364_V368del variant is biologically active and processed normally, while the IL-11R-T306_S308dup variant is retained within the cell and unable to perform signal transduction.
