ATM Regulates Differentiation of Myofibroblastic Cancer-Associated Fibroblasts and Can Be Targeted to Overcome Immunotherapy Resistance.

Unlabelled: Myofibroblastic cancer-associated fibroblast (myoCAF)-rich tumors generally contain few T cells and respond poorly to immune-checkpoint blockade. Although myoCAFs are associated with poor outcome in most solid tumors, the molecular mechanisms regulating myoCAF accumulation remain unclear, limiting the potential for therapeutic intervention. Here, we identify ataxia-telangiectasia mutated (ATM) as a central regulator of the myoCAF phenotype.

[Features of the formation of interzonal connections of the brain according to quantitative electroencephalography in full-term and premature infants].

Objective: To study the features of functional interzonal integration and its dynamics in infants from 0 to 9 months during prospective observation, taking into account the timing gestation, clinical picture and morphological changes on neurosonography (NSG).

Material And Methods: A comprehensive unified examination was carried out in dynamics in 89 infants three times at the age of 3, 6, 9 months and included, in addition to assessing the neurological status, the Denver Developmental Screening Test (DDST), transfontanellar ultrasonography with a vector sensor according to the generally accepted method. We also evaluated the parameters of electroencephalography (EEG) recorded in the waking state with an analysis of background parameters, zonal differences, and the identification of pathological types of activity and calculation of the average coherence power (ACP).

Transcriptional analysis highlights three distinct immune profiles of high-risk oral epithelial dysplasia.

Oral potentially malignant disorders (OPMD) are precursors of oral squamous cell carcinoma (OSCC), and the presence of oral epithelial dysplasia (OED) in OPMD confers an increased risk of malignant transformation. Emerging evidence has indicated a role for the immune system in OPMD disease progression; however, the underlying immune mechanisms remain elusive. In this study, we used immune signatures established from cancer to delineate the immune profiles of moderate and severe OED, which are considered high-risk OPMD.

Safety and Immunogenicity of Combined DNA-Polyethylenimine and Oral Bacterial Idiotypic Vaccine for Patients with B-Cell Non-Hodgkin Lymphoma: A Pilot Study.

We report, in brief, the results of a phase I, non-randomized study of idiotypic DNA vaccination in patients with B-cell non-Hodgkin's lymphoma (ISRCTN31090206). The DNA sequence of lymphoma-derived immunoglobulin variable regions was used as a tumor-specific antigen fused to the potato virus X coat protein. A conjugate of plasmid DNA with polyethylenimine was used for the intramuscular injections, followed by a boost with an oral live-attenuated vaccine carrying the same plasmid.

Targeting the tumor mutanome for personalized vaccination in a TMB low non-small cell lung cancer.

Background: Cancer is characterized by an accumulation of somatic mutations, of which a significant subset can generate cancer-specific neoepitopes that are recognized by autologous T cells. Such neoepitopes are emerging as important targets for cancer immunotherapy, including personalized cancer vaccination strategies.

Methods: We used whole-exome and RNA sequencing analysis to identify potential neoantigens for a patient with non-small cell lung cancer.
