About this Research Topic
Since its discovery, increasing studies have investigated IL-32 role in health and diseases. However, explanations of the specific role are not always consistent, especially before the identification of its isoforms. For example, IL-32 showed different roles in cancer, either enhancing tumor proliferation or suppressing cancer development, depending on the type of cancer and microenvironment. Moreover, the participation of IL-32 has been mentioned in several autoimmune diseases, especially rheumatoid arthritis (RA), atopic dermatitis, inflammatory bowel diseases (IBD), and type 1 diabetes (T1D). This frequently noted roles of IL-32 during the pathogenesis of cancerous, inflammatory, as well as allergic, and infectious diseases, indicating its regulatory role in various conditions. Recently, a number of studies reveal its contribution to neurological disorders such as Alzheimer's disease (AD) and Parkinson’s which could be linked to its initial recognized role in response to hypoxia. Although several insights have been attained into the pro-/anti-inflammatory mechanisms of IL-32 in health and diseases, there are still many doubts to be revealed and answered, starting from identifying the binding partners to the exact regulation of each isoform in different conditions.
Up to now, there are nine transcripts known to be generated from IL-32 mRNA splicing: IL-32α, IL-32β, IL-32δ, IL-32γ, IL-32θ, IL-32ε, IL-32ζ, IL-32η, and small (IL-32s). These isoforms demonstrated varied functions and regulations and yet are not completely understood. One of the goals of this research topic is to collect contributions to characterizing the IL-32, use as a model for different diseases, and consider novel developmental and/or evolutionary connections to fill this gap, to establish exchanges between different scientific disciplines.
