IL-1 receptor antagonist: etiological and drug delivery systems overview

OBJECTIVE

This article is aims to provide an overview of studies reported in the literature to investigate the etiological role of IL-1/IL-1ra in various disease conditions and the different drug delivery systems developed to achieve IL-1ra as a possible therapeutic option.

METHODS

Studies reported in PubMed, Google scholar, and other open-source literature related to etiological involvement of IL-1ra in pathophysiological conditions and various drug delivery schemes developed for IL-1ra for its efficacy evaluation as a possible treatment for different disease conditions were surveyed.

RESULTS AND CONCLUSIONS

The pathophysiological conditions involving IL-1/IL-1 ra spanned CNS-related disorders, Diabetes, Cardiac disorders, Ocular disease conditions, Gastrointestinal conditions, Tumor growth & metastasis, and miscellaneous conditions. The drug delivery systems developed for IL-1ra included a commercial drug product, Gene therapy, Antibody fusions, Extended-release delivery systems, and Pegylated-IL-1ra systems.

Otorhinolaryngological manifestations of autoinflammatory diseases. Systematic review

OBJECTIVES

To detail the main otorhinolaryngological manifestations of autoinflammatory diseases, aiming to contribute to early diagnosis and treatment.

DATA SOURCES

Searches were conducted in PubMed, LILACS, Cochrane Library.

REVIEW METHODS

A systematic review of the medical literature on autoinflammatory diseases was conducted to identify characteristic head and neck manifestations, using PRISMA criteria. Observational studies or systematic reviews with a minimum of 10 cases per disease were included. Qualitative synthesis and a risk assessment were carried out.

RESULTS

Our review included 29 articles that met the inclusion criteria, with 10 to 486 patients per study. Autoinflammatory diseases with characteristic head and neck manifestations included VEXAS syndrome (auricular, nasal, or laryngotracheal chondritis), NPRL3-AID (hearing loss), NPRL12-AID (cervical lymphadenopathies, hearing loss and oral ulcers), HIDSs syndrome (painful cervical nodes and oral ulcers), haploinsufficiency A20 (oral ulcers), TRAPS (pharyngitis, aphthous stomatitis, periorbital edema, and cervical lymphadenopathies), Behcet's disease (oral and pharyngeal ulcers), PFAPA syndrome (recurrent tonsillitis, oral ulcers, and painful cervical adenopathies), Kawasaki disease (cervical nodes, pharyngitis and changes in oral mucosa) and undefined periodic fever (pharyngitis, oral ulcers, and painful cervical nodes).

CONCLUSION

Given their complex diagnosis and unique head and neck manifestations, otolaryngologists must be well-versed in these diseases for early detection and treatment. ENT specialists should consider the possibility of an autoinflammatory disease when encountering symptoms such as auricular, nasal, or laryngeal chondritis, recurrent oral ulcers, painful inflammatory lymphadenopathies, periorbital edema, recurrent pharyngitis, or hearing loss within the context of compatible systemic conditions.

NF-κB in biology and targeted therapy: new insights and translational implications

NF-κB signaling has been discovered for nearly 40 years. Initially, NF-κB signaling was identified as a pivotal pathway in mediating inflammatory responses. However, with extensive and in-depth investigations, researchers have discovered that its role can be expanded to a variety of signaling mechanisms, biological processes, human diseases, and treatment options. In this review, we first scrutinize the research process of NF-κB signaling, and summarize the composition, activation, and regulatory mechanism of NF-κB signaling. We investigate the interaction of NF-κB signaling with other important pathways, including PI3K/AKT, MAPK, JAK-STAT, TGF-β, Wnt, Notch, Hedgehog, and TLR signaling. The physiological and pathological states of NF-κB signaling, as well as its intricate involvement in inflammation, immune regulation, and tumor microenvironment, are also explicated. Additionally, we illustrate how NF-κB signaling is involved in a variety of human diseases, including cancers, inflammatory and autoimmune diseases, cardiovascular diseases, metabolic diseases, neurological diseases, and COVID-19. Further, we discuss the therapeutic approaches targeting NF-κB signaling, including IKK inhibitors, monoclonal antibodies, proteasome inhibitors, nuclear translocation inhibitors, DNA binding inhibitors, TKIs, non-coding RNAs, immunotherapy, and CAR-T. Finally, we provide an outlook for research in the field of NF-κB signaling. We hope to present a stereoscopic, comprehensive NF-κB signaling that will inform future research and clinical practice.
