Antigen receptor ITAMs provide tonic signaling by acting as guanine nucleotide exchange factors to directly activate R-RAS2.

Centro de Biología Molecular Severo Ochoa, Consejo Superior de Investigaciones Científicas, Universidad Autónoma de Madrid, 28049 Madrid, Spain.
The small GTPase R-RAS2 regulates homeostatic proliferation and survival of T and B lymphocytes and, when present in high amounts, drives the development of B cell chronic lymphocytic leukemia. In normal and leukemic lymphocytes, R-RAS2 constitutively binds to antigen receptors through their immunoreceptor tyrosine-based activation motifs (ITAMs) and promotes tonic activation of the phosphatidylinositol 3-kinase (PI3K) signaling pathway. Here, we examined the molecular mechanisms underlying this direct interaction and its consequences for R-RAS2 activity.

January 2025
Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), Madrid, Spain.
Background: Closing the evidence-practice gap for the treatment of acute coronary syndrome (ACS) is central to improving quality of care. Under the European Society of Cardiology (ESC) framework, we aimed to develop updated quality indicators (QIs) for the evaluation of quality of care and outcomes for patients with ACS.
Methods: A Working Group of experts including members of the ESC Clinical Practice Guidelines Task Force for ACS, Acute CardioVascular Care Association and European Association of Percutaneous Cardiovascular Interventions followed the ESC methodology for QI development.
Left Atrial Remodeling and Function in Various Left Ventricular Hypertrophic Phenotypes.
Eur Heart J Cardiovasc Imaging
January 2025
Heart Institute. Department of Cardiology. Cardiovascular Imaging Unit. Hospital Universitari Germans Trias i Pujol, Barcelona, Spain.
Aims: How the underlying etiology and pathophysiology of left ventricular (LV) hypertrophy affects LA remodeling and function remains unexplored. The present study aims to investigate the influence of various hypertrophic phenotypes on LA remodeling and function.
Methods And Results: Patients with LV hypertrophy who underwent cardiac magnetic resonance (CMR) were compared to a control group.
The Role of Multimodality Imaging in Multiple Valvular Heart Diseases. A Clinical Consensus Statement of the European Association of Cardiovascular Imaging (EACVI) of the ESC.
Eur Heart J Cardiovasc Imaging
January 2025
Department of Cardiology, Leiden University Medical Center, Albinusdreef 2, 2300RC Leiden, The Netherlands.
With this document, the European Association of Cardiovascular Imaging (EACVI) provides an Expert Consensus on the role of multi-modality imaging (MMI) in the management of patients with multiple valvular heart disease (MVD). Emphasis is given to the use of MMI to unravel the diagnostic challenges that characterize these patients and to improve risk stratification. Complementing the last European Society of Cardiology and European Association of Cardio-Thoracic Surgery guidelines on valvular heart disease, this Expert Consensus document also outlines how MMI assessment should form an integral part of the multi-disciplinary heart team discussion for patients with MVD to help with complex decision-making regarding the choice and timing of treatment.
