O-glycan expression is more granular but relatively evenly distributed on positive cells. While N-glycans are expressed on all cells, sialyl-T antigen expression exhibits a wide spectrum of variation with some cells being strongly positive and some cells being almost completely negative. The different...
While these results are encouraging, longer follow-up is required as well as analyses of significance of biomarkers such as PD-L1 expression and tumour mutation burden.doi:10.1136/thoraxjnl-2019-214409Alice DaviesBMJ Publishing Group Ltd and British Thoracic SocietyThorax...
PD-L1 assessment for anti-PD-1 and anti-PD-L1 treatment is currently prescribed by the FDA and EMA in two indications: tumors of platinum-ineligible patients in the first line metastatic setting have to show PD-L1 expression levels of Ventana IC ≥5% or CPS ≥10. Importantly, recently Gene...
The classic subtype refers to the usual recognized form of SCLC, with typical morphology, expression of neuroendocrine (NE) properties and a non-adherent growth pattern in vitro. Variant subtype of SCLC The variant subtype, often recognized after therapy, is characterized by larger cells with promin...
(TILs). Additionally, adoptive T cell transfer of CD8 T cells, associated with TNF production, can lead to melanoma dedifferentiation and the expression of the CD73 ectonucleotidase. The TNF-driven expression of immunosuppressive molecules in the tumor microenvironment, along with AICD of CD8+ TILs...
CD80/CD86 is expressed on mature dendritic cells (DCs). Tregs can down-regulate the expression of CD80/CD86 on DCs through CTLA-4-dependent trogocytosis, increase the expression of free PD-L1, promote the binding of Tregs-DCs and the formation of immune synapse, thereby interfere with antigen...
“immunogenicity of low molecular weight organic chemicals is dependent on modification of self-proteins,” evolved from Landsteiner and Jacob’s discovery of a correlation between the reactivity of dinitro-halogenated benzenes and their sensitization potential. The hypothesis rapidly evolved to encompass ...

In fact, genomics screening has quickly become a standard of care in non–small cell lung cancer as the National Comprehensive Cancer Network’s 2023 principle of molecular and biomarker analysis guidelines have recommended nine genomic screening biomarkers along with PD-L1 expression for therapeutic ...
The ORR was 63 % (32/51 pts) in patients with PD-L1 ≥ 50 %, indicating that this combination is well tolerated [93]. Olomorasib in combination with pembrolizumab from the LOXO-RAS-200001 study cohorts B4 and G with KRAS G12C mutated NSCLC of any PD-L1 expression showed ORR of 77...
