ADWX 1
Based on 1 publication(s) in Google Scholar
ADWX 1 is a new peptide inhibitor that is potent and selective for Kv1.3 with an IC50 value of 1.89 pM. ADWX 1 inhibits Kv1.3 channel activity specifically to inhibit both the initial calcium signaling and NF-κB activation. ADWX 1 ameliorates the disease in rats of experimental autoimmune encephalomyelitis (EAE) models. ADWX 1 can be used to study T cell-mediated autoimmune diseases.

In Vitro
ADWX 1 (1,10 nM, 1 h) inhibits IL-2 and IFN-γ productions, and inhibits humans CD4+ CCR7- TEM cells activation selectively[2].
ADWX 1 (1,10 nM, 50 min) reduces [Ca2+] in activated CD4+ CCR7- TCM cells from EAE rats[2].
ADWX 1 (1,10 nM, 1 h) reduces NF-κB activation and suppresses Kv1.3 expression at both mRNA and protein levels preferentially in myelin basic protein (MBP) (HY-P77995)-stimulated CD4+ CCR7- T cells from EAE rats[2].
ADWX 1 (1,10 nM, 3 days) suppresses Th17 activation but not differentiation in CD4+ CCR7- T cells[2].

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

Research Protocol for Cancer Immunology
Cancer immunology studies how the immune system recognizes, suppresses, edits, or fails to eliminate malignant cells through tumor antigen release, antigen presentation, T-cell priming, immune trafficking, tumor-cell killing, and feedback inhibition in the tumor microenvironment. The cancer-immunity cycle links tumor antigenicity, dendritic-cell priming, CD8+ T-cell infiltration, cytotoxic function, and immune-checkpoint regulation to tumor rejection or immune escape. Immune-checkpoint pathways such as PD-1/PD-L1 and CTLA-4 suppress antitumor T-cell activity and can be therapeutically blocked, but many tumors remain resistant because of poor antigen presentation, weak T-cell infiltration, suppressive myeloid cells, regulatory T cells, and tumor-intrinsic immune-exclusion programs. Unresolved questions include which immune-cell states predict response, how tumor-intrinsic pathways exclude immune cells, how myeloid suppression limits checkpoint blockade, and which combination strategies
