AI Article Synopsis

  • ACE is a zinc-dependent enzyme that regulates blood pressure by converting angiotensin I to angiotensin II, and it has other physiological effects beyond just blood pressure control.
  • The overexpression of ACE affects the immune system by enhancing the function of macrophages and neutrophils, leading to improved antitumor and antimicrobial responses.
  • Understanding ACE's role in immune cell activity may offer potential therapeutic strategies for treating infections and cancers.

Article Abstract

Angiotensin-converting enzyme (ACE) is a zinc-dependent dicarboxypeptidase with two catalytic components, which has an important role in regulating blood pressure by converting angiotensin I to angiotensin II. ACE breaks down other peptides besides angiotensin I and has a variety of physiological effects together with renal growth and reproduction in men. ACE also acts on innate and acquired immune systems by affecting macrophage and neutrophil function, and these outcomes are exacerbated due to the overexpression of ACE. Overexpression of ACE in macrophages imposes antitumor and antimicrobial response, and it enhances the ability of neutrophils to produced super peroxide that has a bactericidal effect. ACE is also known to contribute to the expression of Major Histocompatibility Complex (MHC) class I and MHC class II peptides through enzymatic alterations of these peptides. Apprehending the expression of ACE and its effects on myeloid cell (myelogenous cells) activity can be promising in therapeutic interventions, including treatment of infection and malignancy.

Background: SARS-CoV-2 responsible for the COVID-19 pandemic, infiltrates the human body by binding to the ACE2 receptor in the respiratory system cell membranes, leading to severe lung tissue damage. An analog of ACE2, ACE1, has gained attention due to its well-known Deletion/Insertion (D/I) polymorphism, which seems to be associated with COVID-19 outcomes. This study aims to reveal the allelic and genotypic frequencies of the rs4646994 polymorphism in the Moroccan population and investigate the association between COVID-19 outcomes and both genotypic and demographic data.

Introduction: Cardiovascular disease is the commonest cause of death in Turner syndrome (TS) for which, arterial hypertension has a direct influence and is a key modifiable risk factor.

Objective: To investigate the prevalence and patterns of hypertension diagnosis and management in adult patients with TS who are registered in a large international multicentre database (TS-HTN study).

Methods: Retrospective multi-centre observational study of patients aged ≥18 years, included in the I-TS (International-TS) registry (2020-2022) utilising registry and participating centre collected data.

CXCL12 ameliorates neutrophilia and disease severity in SARS-CoV-2 infection.

J Clin Invest

January 2025

Department of Microbiology and Immunology, University of Iowa, Iowa City, United States of America.

Neutrophils, particularly low-density neutrophils (LDNs), are believed to contribute to acute COVID-19 severity. Here, we showed that neutrophilia can be detected acutely and even months after SARS-CoV-2 infection in patients and mice, while neutrophil depletion reduced disease severity in mice. A key factor in neutrophilia and severe disease in infected mice was traced to the chemokine CXCL12 secreted by bone marrow cells and unexpectedly, endothelial cells.

This study aimed to investigate the changes in the bioactive peptides (BPs) of buffalo milk cheese (BMC) within 15 days of storage. A total of 3605 peptides were identified in the BMC, with 260 peptides remaining stable for 15 days. Among these, the peak intensities of all reported BPs (9 peptides) increased on the 15th day.

Coronavirus disease 2019 (COVID-19) still causes death in elderly and immunocompromised individuals, for whom the sustainability of the vaccine response may be limited. Antiviral treatments, such as remdesivir or molnupiravir, have demonstrated limited clinical efficacy. Nirmatrelvir, an acute respiratory syndrome coronavirus 2 (SARS-CoV-2) major protease inhibitor, is clinically effective but has been associated with viral rebound and antiviral resistance.
