Proteinase inhibitors (PIs) from the seeds of bitter gourd (Momordica charantia L.) were identified as strong inhibitors of Helicoverpa armigera gut proteinases (HGP). Biochemical investigations showed that bitter gourd PIs (BGPIs) inhibited more than 80% HGP activity. Electrophoretic analysis revealed the presence of two major proteins (BGPI-1 and-2) and(More)
Several components of the mosquito immune system including the RNA interference (RNAi), JAK/STAT, Toll and IMD pathways have previously been implicated in controlling arbovirus infections. In contrast, the role of the phenoloxidase (PO) cascade in mosquito antiviral immunity is unknown. Here we show that conditioned medium from the Aedes albopictus-derived(More)
BACKGROUND Non-segmental vitiligo (NSV) results from autoimmune destruction of melanocytes. The altered levels of various cytokines have been proposed in the pathogenesis of vitiligo. However, the exact immune mechanisms have not yet been fully elucidated. OBJECTIVES To investigate the role of epidermal and systemic cytokines in active and stable NSV(More)
Dermal fibroblasts secrete various growth factors which are important for skin pigmentation. Imbalance in the synchronization of epidermal and dermal cells in the skin can play vital role in the pathogenesis of pigmentary disorder vitiligo. Therefore, our objective was to check the lesional fibroblasts for any abnormality and senescence in non-segmental(More)
