Verma NK
Oncogenic activation of STAT3 pathway drives PD-L1 expression in natural killer/T cell lymphoma.
Mature T-cell lymphomas, including peripheral T-cell lymphoma (PTCL) and extranodal NK/T-cell lymphoma (NKTL), represent a heterogeneous group of non-Hodgkin lymphomas with dismal outcomes and limited treatment options. To determine the extent of involvement of JAK/STAT pathway in this malignancy, we performed targeted capture sequencing of 188 genes in this pathway in 171 PTCL and NKTL cases.
ReadInfluence of pH on the activity of thrombin-derived antimicrobial peptides
The wound environment is characterized by physiological pH changes. Proteolysis of thrombin by wound-derived proteases, such as neutrophil elastase, generates antimicrobial thrombin-derived C-terminal peptides (TCPs), such as HVF18 (HVFRLKKWIQKVIDQFGE). Presence of such TCPs in human wound fluids in vivo, as well as the occurrence of an evolutionarily conserved His residue in the primary amino acid sequence of TCPs, prompted us to investigate the pH-dependent antibacterial action of HVF18, as well as of the prototypic GKY25 (GKYGFYTHVFRLKKWIQKVIDQFGE).
