Although immune checkpoint inhibitors (ICIs) have achieved unprecedented results in melanoma, the biological features of the durable responses initiated by these drugs remain unknown. Here we show the genetic and phenotypic changes induced by treatment with programmed cell death-1 (PD-1) blockade in a genetically engineered mouse model of melanoma…[Read more]

In addition, homozygous mice showed learning and memory impairments in the trace fear conditioning (FC) at both ages, and task performance strongly correlated with REMS amount at 12 months. Finally, histologic analyses revealed that amyloid-β accumulation in the pontine tegmental area and ventral medulla followed a course similar to that of the RE…[Read more]

The multivariate analysis confirmed that not only N2 category and the value of CCI above 4 are negative prognostication factors, but also RDW-SD above 43 fL (P=0.00007) and PLR above 138 (P=0.001) are such negative factors of survival prognosis. Conclusions RDW-SD is an independent and significant prognostic factor of patients’ survival operated…[Read more]
