Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Structures of a deltacoronavirus spike protein bound to porcine and human receptors

open access: yesNature Communications, 2022
Porcine deltacoronavirus (PDCoV) can experimentally infect a variety of animals. Human infection by PDCoV has also been reported. Consistently, PDCoV can use aminopeptidase N (APN) from different host species as receptors to enter cells.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Predicted 3D Models of the SARS-CoV-2 Spike Protein Membrane Proximal External Region and Transmembrane Domain

open access: yes, 2020
The transmembrane helix domain (TMD), membrane proximal external region (MPER) and part of heptad repeat 2 (HR2) domain in SARS-CoV-2 spike protein were modelled using a constrained fold-and-dock strategy.

Structure, Function, and Evolution of Coronavirus Spike Proteins [PDF]

open access: yesAnnual Review of Virology, 2016
The coronavirus spike protein is a multifunctional molecular machine that mediates coronavirus entry into host cells. It first binds to a receptor on the host cell surface through its S1 subunit and then fuses viral and host membranes through its S2 subunit.

Spike protein of SARS-CoV-2 Omicron variant: An in-silico study evaluating spike interactions and immune evasion

open access: yesFrontiers in Public Health, 2022
BackgroundThe fundamentals of the infectivity and immune evasion of the SARS-CoV-2 Omicron variant are not yet fully understood. Here, we carried out an in-silico study analyzing the spike protein, the protein electrostatic potential, and the potential ...

Assessment of mutations on RBD in the Spike protein of SARS-CoV-2 Alpha, Delta and Omicron variants

open access: yesScientific Reports, 2022
The severe acute respiratory syndrome (SARS) coronavirus 2 (CoV-2) variant Omicron spread more rapid than the other variants of SARS-CoV-2 virus. Mutations on the Spike (S) protein receptor-binding domain (RBD) are critical for the antibody resistance ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Engineered protein subunit COVID19 vaccine is as immunogenic as nanoparticles in mouse and hamster models

open access: yesScientific Reports
Initial studies on the immunogenicity of SARS-CoV-2 (CoV-2) S glycoprotein (“spike”) as a protein subunit vaccine suggested sub-optimal efficacy in mammals.

Structural insights on the differentiation and reversion of conformational changes in SARS-CoV-2 spike protein models across variants occurring from December, 2019 to November, 2021

open access: yesImmunoInformatics
Conformational changes in the SARS-CoV-2 spike protein are critical for understanding viral evolution. In this study, we provide comparative structural and electrostatic analyses across variants, revealing both differentiation and reversion patterns not ...
