Article Abstract

Immunotherapy of melanoma is aimed to mobilize cytolytic CD8+ T cells playing a central role in protective immunity. Despite numerous clinical vaccine trials, only few patients exhibited strong antigen-specific T-cell activation, stressing the need to improve vaccine strategies. For a rational development, we propose to focus on molecularly defined vaccine components, and evaluate their immunogenicity with highly reproducible and standardized methods for ex vivo immune monitoring. Careful immunogenicity comparison of vaccine formulations in phase I/II studies allow to select optimized vaccines for subsequent clinical efficacy testing in large scale phase III trials.

Molecular Regulation of Cardiomyocyte Maturation.

Curr Cardiol Rep

Department of Cell, Developmental and Regenerative Biology, Icahn School of Medicine at Mount Sinai, 1470 Madison Avenue, New York, NY, 10029, USA.

Purpose Of The Review: This review aims to discuss the process of cardiomyocyte maturation, with a focus on the underlying molecular mechanisms required to form a fully functional heart. We examine both long-standing concepts associated with cardiac maturation and recent developments, and the overall complexity of molecularly integrating all the processes that lead to a mature heart.

Recent Findings: Cardiac maturation, defined here as the sequential changes that occurring before the heart reaches full maturity, has been a subject of investigation for decades.

Synthetic lethality offers a robust strategy for discovering the next generation of precision medicine therapies tailored for molecularly defined patient populations. MAT2A inhibition is synthetically lethal in several cancers that exhibit a homozygous deletion of -methyl-5'-thioadenosine phosphorylase (MTAP). Herein, we report the identification of novel MAT2A inhibitors featuring a spiral ring to circumvent the C-N atropisomeric chirality utilizing structure-based drug design.

Attempts to activate an anti-tumor immune response in glioblastoma (GBM) have been met with many challenges due to its inherently immunosuppressive tumor microenvironment. The degree and mechanisms by which molecularly and phenotypically diverse tumor-propagating glioma stem cells (GSCs) contribute to this state are poorly defined. In this study, our multifaceted approach combining bioinformatics analyses of clinical and experimental datasets, single-cell sequencing, and molecular and pharmacologic manipulation of patient-derived cells identified GSCs expressing immunosuppressive effectors mimicking regulatory T cells (Tregs).

Background: Anaplastic lymphoma kinase (ALK)-rearranged renal cell carcinoma (ALK-RCC) is a rare molecularly defined tumor entity included in the fifth edition of the World Health Organization Classification of Tumors. It is characterized by rearrangement of the ALK gene with various fusion partner genes, which most commonly results in oncogenic fusion proteins leading to ALK activation.

Case Presentation: A 30-year-old Chinese man underwent partial nephrectomy for a left renal tumor measuring 5 cm in diameter.

The bed nucleus of the stria terminalis (BNST) is involved in feeding, reward, aversion, and anxiety-like behavior. We identify BNST neurons defined by the expression of vesicular glutamate transporter 3, VGluT3. VGluT3 neurons were localized to anteromedial BNST, were molecularly distinct from accumbal VGluT3 neurons, and co-express vesicular GABA transporter (VGaT).
