Proteome News and Research

RSS

The proteome is the entire complement of proteins expressed by a genome, cell, tissue or organism. More specifically, it is the expressed proteins at a given time point under defined conditions. The term is a blend of proteins and genome.

Mechanism of SARS-CoV-2 Nsp1 interaction with ribosomal complexes

In a recent study posted to the bioRxiv* preprint server, the team of researchers explored the protein-protein interaction between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) non-structural protein 1 (Nsp1) and host 40S and 43S ribosomal subunits.

Hollings researcher receives grant to fight complications after pediatric bone marrow transplant

MUSC Hollings Cancer Center researcher Sophie Paczesny, M.D., Ph.D., recently received a four-year grant from the National Heart, Lung, and Blood Institute to investigate solutions to help doctors to fight complications after pediatric bone marrow transplantation (BMT).

First unbiased proteome scale study expands the number of known transcriptional activators

Also known as transcriptional activators for their ability to induce transcription of genes into RNA messages, these proteins are essential for the cells to function properly. Yet little is known about these proteins, and it wasn't clear how many activators there might be in human cells – until now.

New COVID-19 test can determine if individuals have been vaccinated, infected, both, or neither

Researchers have created a new T cell assay that allows discrimination of COVID-19 infection and vaccination, as well as the order in which these occurred.

Measuring T cell responses to SARS-CoV-2 vaccination and infection in healthcare workers with two different assays

The purpose of this study was to compare the OI TSPOT with the in-house PITCH ELISpot for reporting T cell responses specific to SARS-CoV-2 spike and structural proteins.

Non-mutated ApoE protein linked to dementia

A team of researchers from the University of Kentucky's Sanders-Brown Center on Aging is working to identify new proteins that are destructive to the brain.

Targeting SARS-CoV-2 M protein may help ease severity of COVID-19

A new study, published on the medRxiv preprint server, focused on the production of human CD4+ T cell lines (TCLs), reactive to either S or M protein, and analyzed if the S and M structural proteins had intrinsic differences in driving antigen-specific CD4+ T cell responses.

Endosomal sorting of neuropilin-1 in SARS-CoV-2 infectivity

A study recently identified Neurolipin-1 or NRP1, a host factor for SARS-CoV-2 infection, as a cargo retrograde-transported by the ESCPE-1.

SARS-CoV-2 infection and vaccination-induced T cells cross-recognize Omicron

In a recent study posted to the Nature In Review* preprint server, researchers performed a comprehensive, in-depth comparison of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific T cell epitope repertoire following natural infection of coronavirus disease 2019 (COVID-19) compared to messenger ribonucleic acid (mRNA) vaccinations.

Scientists explore how proteins bind with specific companions inside cells

Despite its minute size, a single cell contains billions of molecules that bustle around and bind to one another, carrying out vital functions. The human genome encodes about 20,000 proteins, most of which interact with partner proteins to mediate upwards of 400,000 distinct interactions.

An algorithm to predict host cleavage targets of SARS-CoV-2 3CLPro

In a recent study posted to the bioRxiv* preprint server, researchers developed a novel bioinformatic algorithm to predict host cleavage targets of the SARS-CoV-2 3C-like protease (3CLPro).

Researchers construct models to predict SARS-CoV-2 mutable and constrained positions

In a study published in PNAS, researchers have attempted to create a model that can successfully predict which positions are likely to mutate in the future.

New and improved method for imaging the structure of neural connections

The glory of tissue expansion technologies is that when structures, such as proteins that build nerve cell connections, are too small for a microscope to resolve, clever chemistry can make everything bigger and easier to see.

Lack of evidence cross-reactive adaptive immune response is mechanism underlying COVID vaccine-induced myocarditis

Recently, the researchers from the USA, in their study published in the journal EBioMedicine, have conducted a sequence identity comparison and 3D protein structure comparison between the SARS-CoV-2 spike protein-derived peptides/protein and myocarditis-associated antigens and have found no significant enrichment in the frequency of spike-derived peptides similar to myocarditis-associated antigens that could have resulted in adaptive autoimmune responses leading to myocarditis.

Study finds T cell response mostly conserved against SARS-CoV-2 Omicron variant following infection or vaccination

A new preprint examines the extent of protection offered by T cell responses to primary vaccination and/or natural infection with the virus.

SARS-CoV-2 Omicron variant leads to widespread escape from neutralizing antibody responses

A new study reported the neutralization of Omicron by a large panel of sera collected from convalescent early pandemic, Alpha, Beta, Gamma and Delta infected individuals, as well as among vaccinees receiving three doses of the Oxford/AstraZeneca (AZD1222) or the Pfizer BioNtech (BNT16b2) vaccines.

P323L mutations in SARS-CoV-2 are highly predictive of the emergence of new variants

In a new study, findings suggest that in some cases, tracking the distribution and frequency of SARS-CoV-2 minor variant genomes at a population level would help in predicting the emergence of a new dominant viral genome sequence.
