The Protective HIV-1 Envelope gp41 Antigen P1 Acts as a Mucosal Adjuvant Stimulating the Innate Immunity

open access: yesFrontiers in Immunology, 2021
Mucosal nasal vaccine development, although ideal to protect from pathogens invading mucosally, is limited by the lack of specific adjuvant. We recently used P1, a conserved region of HIV-1 gp41-envelope glycoprotein, as efficient antigen in a ...

S100A8-mediated metabolic adaptation controls HIV-1 persistence in macrophages in vivo

open access: yesNature Communications, 2022
HIV-1 eradication is hindered by viral persistence in different cell reservoirs, including circulatory CD4+ T-cells and tissue-resident macrophages. Here, by analyzing male genital mucosa from cART-suppressed HIV1-infected individuals, Real et al.

Protocol to detect infectious SARS-CoV-2 at low levels using in situ hybridization techniques

open access: yesSTAR Protocols, 2023
Summary: Low and persistent levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA/protein/virus can be detected in clinical samples months after infection, possibly related to the emergence of SARS-CoV-2 variants or development of ...

Antibody-Dependent Cellular Phagocytosis of HIV-1-Infected Cells Is Efficiently Triggered by IgA Targeting HIV-1 Envelope Subunit gp41

open access: yesFrontiers in Immunology, 2020
Antibodies mediate a broad array of non-neutralizing Fc-mediated functions against HIV-1 including antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP).

Native CGRP Neuropeptide and Its Stable Analogue SAX, But Not CGRP Peptide Fragments, Inhibit Mucosal HIV-1 Transmission

open access: yesFrontiers in Immunology, 2021
BackgroundThe vasodilator neuropeptide calcitonin gene-related peptide (CGRP) plays both detrimental and protective roles in different pathologies. CGRP is also an essential component of the neuro-immune dialogue between nociceptors and mucosal immune ...

Antibody Fc-chimerism and effector functions: When IgG takes advantage of IgA

open access: yesFrontiers in Immunology, 2023
Recent advances in the development of therapeutic antibodies (Abs) have greatly improved the treatment of otherwise drug-resistant cancers and autoimmune diseases. Antibody activities are mediated by both their Fab and the Fc.

Distinct Expression Patterns of Interleukin-22 Receptor 1 on Blood Hematopoietic Cells in SARS-CoV-2 Infection

open access: yesFrontiers in Immunology, 2022
The new pandemic virus SARS-CoV-2 is characterized by uncontrolled hyper-inflammation in severe cases. As the IL-22/IL-22R1 axis was reported to be involved in inflammation during viral infections, we characterized the expression of IL-22 receptor1, IL ...

IgA Targeting Human Immunodeficiency Virus-1 Envelope gp41 Triggers Antibody-Dependent Cellular Cytotoxicity Cross-Clade and Cooperates with gp41-Specific IgG to Increase Cell Lysis

open access: yesFrontiers in Immunology, 2018
The protective efficacy of human immunodeficiency virus-1 (HIV-1) antibodies (Abs) remains mostly correlated with their in vitro neutralizing activity engaging their Fab region.

Specific Host Signatures for the Detection of Tuberculosis Infection in Children in a Low TB Incidence Country

open access: yesFrontiers in Immunology, 2021
Diagnosis of tuberculosis (TB) in children remains challenging due to unspecific clinical presentation and low bacillary load. In low TB incidence countries, most cases are diagnosed by a contact screening strategy after exposure to an index TB case. Due
