Gout is an inflammatory arthritis due to the joint deposition of monosodium urate (MSU) crystals. Phagocytosis of MSU crystals by tissue macrophages results in the generation of reactive oxygen species (ROS) and production of inflammatory cytokines and chemokines. Colchicine use in gout is limited by severe toxicity. CD44 is a transmembrane glycoprotein that is highly expressed in tissue macrophages and may be involved in gout pathogenesis. The P6 peptide is a 20-amino acid residue peptide that binds to CD44. We hypothesized that the conjugation of colchicine to the P6 peptide would reduce its off-target cytotoxicity while preserving its anti-inflammatory effect. …

Systemic sclerosis is a chronic, fibrotic disorder associated with high disease-specific mortality and morbidity. Cutaneous manifestations include dermal thickening and obliteration of dermal adipose tissue. The efficacy of function-blocking Rhamm peptides, NPI-110 and NPI-106, were tested in reducing skin fibrosis and promoting adipogenesis in a bleomycin-induced mouse model of systemic sclerosis. NPI-110 reduced both visible measures of fibrosis (dermal thickness, collagen density, and fibril bundling) and mRNA expression of pro-fibrotic genes (Tgfb1, c-Myc, Col1a1, Col3a1). While there was no measurable change in dermal adipose thickness, NPI-110 treatment upregulated Perilipin mRNA and Adiponectin protein expression and is therefore hypothesized to …
