The aim of the study was to assess expression immune checkpoint inhibitor programmed death-ligand 1 (PD-L1) in equine sarcoids (ES). Programmed is expressed by various cancer cells block T cell–mediated elimination tumor cells. Antibodies targeting human PD-L1 were tested immunohistochemistry for their cross-reactivity with using formalin-fixed, paraffin-embedded tissues. Our results do not sup...

Apoptosis or programmed cell death (PCD) is a physiological process characteristic of pluricellular organisms leading to self-destruction of the cell. It is therefore involved in development, homeostasis and host defense. However, a significant difference has been shown between mammalian cell apoptosis and non-mammalian cell apoptosis: mitochondria are implicated only in the former. Execution o...

BACKGROUND Antibody therapy targeting programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) is a promising therapy in human cancer, but only limited information on PD-L1 expression in canine tumors is available. MATERIALS AND METHODS PD-L1 expression was examined in 31 canine tumor cell lines of various origins by flow cytometry and western blotting, and in canine tumor an...

objective: the anti-cancer properties of curcumin, a poliphenol extract from the rhizome of curry, has been confirmed by many investigators. however, low levels of uptake, tissue distribution and rapid metabolism has limited its application as an anti-cancer drug. this study is aimed at increasing curcumin's water solubility due to a biodegradable, neutral and non-toxic micellar nano-carrier ca...

Programmed death receptor 1 (PD-1) is an important signaling molecule often involved in tumor-mediated suppression of activated immune cells. Binding of this receptor to its ligands, B7-H1 (PD-L1) and B7-DC (PD-L2), attenuates T cell activation, reduces IL-2 and IFN-γ secretion, decreases proliferation and cytotoxicity, and induces apoptosis. B7-DC-Ig is a recombinant protein that binds and tar...

Oesophageal cancer (OC) is the seventh most common malignancy worldwide, and there are few effective treatment options for advanced OC. Fluoropyrimidine platinum-based chemotherapy has been standard first-line oesophageal squamous cell carcinoma (OSCC) but survival outcomes poor. Therefore, a need to develop new, more drugs. Immune checkpoint inhibitors (ICIs) have emerged as new several malign...

Programmed cell death ligand 1 (PDL1, also known as B7H1) is a cell-surface protein that suppresses the cytotoxic CD8(+) T-cell-mediated immune response. PDL1 expression and its clinical relevance in sarcomas are not well understood. Therefore, we sought to measure RNA expression levels for PDL1 in 38 clinically annotated osteosarcoma tumor samples and aimed to determine if PDL1 expression corr...

Experimental allergic encephalomyelitis is a mouse model of human multiple sclerosis with similar pathology and pathogenesis. Th1 cells play an important role in the pathogenesis of experimental allergic encephalomyelitis. This study determined the potential effect of programmed cell death 1 ligand 1 in the pathogenesis of experimental allergic encephalomyelitis induced by injecting myelin olig...
