While the SARS-CoV-2 pandemic is heavily hitting the world, it is of extreme importance that significantin vitroobservations guide the quick set up of clinical trials. In this study, we evidence that the anti-SARS-CoV2 activity of a clinically achievable hydroxychloroquine concentration is maximized only when administered before and after the infection of Vero E6 and Caco-2 cells. This suggests that only a combined prophylactic and therapeutic use of hydroxychloroquine may be effective in limiting viral replication in patients.

The initial interplay between HIV and mucosal innate immunity

Valeria Caputo, Martina Libera, Sofia Sisti, Benedetta Giuliani, Roberta A. Diotti, Elena Criscuolo

Summary: Human Immunodeficiency Virus (HIV) remains a major global health issue, and the mucosal innate immune response and microbiota play crucial roles in HIV infection. The mucosae act as a physical barrier that can be compromised by the virus, leading to innate immune response, and the mucosal microbiota can influence the development of opportunistic infections. However, a proper characterization of mucosal innate immune response and microbiota is still lacking, and further studies are needed to understand their potential in vaccine development.

Summary: Flavonoids, such as baicalein, have been shown to inhibit the key enzyme 3CLpro of SARS-CoV-2 and exhibit antiviral activity against multiple coronaviruses.

Smallpox vaccination-elicited antibodies cross-neutralize 2022-Monkeypox virus Clade II

Elena Criscuolo, Benedetta Giuliani, Roberto Ferrarese, Davide Ferrari, Massimo Locatelli, Massimo Clementi, Nicasio Mancini, Nicola Clementi

Summary: Since May 2022, there have been reported cases of monkeypox virus (MPXV) infections in non-endemic countries, leading to the most severe outbreak described so far. Despite genetic variations in the current outbreak's isolated viruses, serum antibodies produced by first-generation smallpox vaccines have shown the ability to neutralize the current MPXV more than 40 years after vaccination.

Summary: This report describes a case of a 34-year-old patient with active SARS-CoV-2 infection and high-risk leukemia who underwent allogeneic hematopoietic stem cell transplantation. Timely anti-SARS-CoV-2 preventive therapies and prompt management of transplant-related complications resulted in a favorable outcome.

Dual-Domain Reporter Approach for Multiplex Identification of Major SARS-CoV-2 Variants of Concern in a Microarray-Based Assay

Francesco Damin, Silvia Galbiati, Nicola Clementi, Roberto Ferrarese, Nicasio Mancini, Laura Sola, Marcella Chiari

Summary: Since the emergence of the COVID-19 pandemic, monitoring and tracking the distribution of SARS-CoV-2 variants is crucial for adjusting public health interventions. However, genome sequencing is not cost-effective and rapid. We have developed a microarray-based assay that can accurately detect known viral variants present in clinical samples by detecting mutations in the Spike protein gene. This assay can genotype the WHO-reported variants of concern (VOCs) in patient samples.

Inhibiting immunoregulatory amidase NAAA blocks ZIKV maturation in Human Neural Stem Cells

Summary: Recent evidence suggests that lipids play a crucial role in viral infections by altering host lipids and interfering with lipogenesis. In the case of Zika virus (ZIKV), inhibiting N-Acylethanolamine acid amidase (NAAA) reduces viral replication and blocks virus maturation. This study highlights NAAA as a potential target for combating ZIKV infection.

Summary: The integrity of the gut barrier is crucial for regulating the interaction between the microbiota and the immune system, and preventing inflammation and autoimmunity. Administration of an anti-inflammatory diet to restore gut barrier integrity can prevent the development of autoimmune Type 1 Diabetes (T1D).

' Onghia, Bianca Giuliani, Elena Criscuolo, Matteo Castelli, Nicola Clementi, Massimo Clementi, Nicasio Mancini, Tiziana Bonaldi, Stefano Gustincich, Tommaso Leonardi, Gian Gaetano Tartaglia, Francesco Nicassio

Summary: This study predicts and validates the host proteins that specifically bind to the terminal regions of SARS-CoV-2 RNA using the catRAPID algorithm and RNA-protein interaction detection coupled with mass spectrometry technology. It also discovers extensive post-transcriptional modifications in the viral RNA and highlights the significance of pseudouridine synthases in the viral life cycle.
