  • IL-18 Therapies Targeting Inflammatory Disease

    Thu, 25 May 2023 16:43:35 GMTBy: (Beata Boczkowska, Ph.D.)

    Interleukin-18 (IL-18) is an effective pro-inflammatory cytokine for the host defense against infections and controls the innate and acquired immune response. Both hematopoietic and non-hematopoietic cells, including monocytes, macrophages, keratinocytes, and mesenchymal cells produce IL-18. IL-18 can increase Th1 responses and is critical for IFN-gamma production. IL-18 is regulated by IL-18BP by inhibiting the biological activity of IL-18, thereby reducing IFN-gamma production in turn suppressing the Th1 immune responses. The dysregulation of the IL-18/IL-18BP balance is associated with multiple biological effects and pathological outcomes (1). Both IL-18 and IL18BP are connected to developing psoriasis, atopic dermatitis (AD), lupus erythematosus (LE), and other inflammatory skin diseases. Still, IL-18 is more prominently involved with chronic inflammation and autoimmune disease such as inflammatory bowel diseases, type I diabetes mellitus, chronic liver disease, adult-onset Still’s disease, hemophagocytic syndrome, rheumatoid arthritis, and idiopathic thrombocytopenic purpura.

  • Crucial Niche Factors for Organoid Cultures

    Fri, 17 Mar 2023 20:34:51 GMTBy: (Bindi M. Doshi, PhD)

    Organoids are 3D structures made up of cells that replicate the structure and function of tissues and organs. Organoids can be derived from stem cells or tissue-specific progenitor cells. A stem cell niche is the specific microenvironment that regulates the stem cell behaviors. Many researchers try to recreate these stem cell niches in vitro. However, it is difficult to create the appropriate cell culture conditions for stem cell growth. Here we discuss current advances made to help create and maintain organoid cultures. Read more
