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.

Newly identified coronavirus epitopes induce robust antibody responses

Researchers at the University of Wisconsin-Madison have conducted a study showing that infection with severe acute respiratory syndrome coronavirus 2 (SARS-C0V-2) triggers robust immune responses to epitopes across the full viral proteome.

Exciting findings on CD8 T cell response in recovered COVID patients

An international team of scientists has identified novel T cell-recognized epitopes spanning different proteins of severe acute respiratory syndrome coronavirus 2 in COVID-19 recovered patients. The scientists have also revealed phenotypical characteristics of the T cell population.

Study determines frequency and patterns of T-cell escape mutations in HIV patients undergoing antiretroviral therapy

Immune cells that can recognize residual HIV-infected cells in people living with HIV (PLWH) who take antiretroviral therapy (ART) remain active for years, says a new study published today in eLife.

New approach to reveal high-resolution protein structural details

The number of proteins in the human body, collectively known as the proteome, is vast. Somewhere between 80,000 and 400,000 proteins circulate in our cells, tissues and organs, carrying out a broad range of duties essential for life.

New findings could improve investigation of T cell response to COVID-19

Researchers in the United States have made an important discovery about the processing and presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral peptides that provides a better understanding of the immune response to coronavirus disease 2019 (COVID-19) and may help facilitate the design of improved vaccines.

Metabolite signature reveals signs of multi-organ damage in COVID-19 patients

SARS-CoV-2, the virus responsible for COVID-19, can cause a wide range of symptoms, from none at all to severe respiratory stress, multi-organ failure and death.

The T cell responses in COVID-19 recovered individuals

A recent study demonstrates that functional CD4+ and CD8+ T cells specifically targeting the entire proteome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain active in individuals who have recovered from severe or mild coronavirus disease 2019 (COVID-19). Moreover, the magnitude of T cell response is correlated with the antibody response. The study is published in the journal Nature Immunology.

Important research on SARS-CoV-2 proteins using proximity labeling

A team of Canadian scientists has recently discovered a wide-range interaction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and host proteins using proximity-dependent biotinylation approaches.

Study shows how genetic data can be used to prioritize drug targets for complex diseases

An innovative genetic study of blood protein levels, led by researchers in the MRC Integrative Epidemiology Unit at the University of Bristol, has demonstrated how genetic data can be used to support drug target prioritisation by identifying the causal effects of proteins on diseases.

Study shows what happens in the fetal brain affected by congenital Zika syndrome

Zika virus infection during pregnancy can cause severe abnormalities in the fetus, including malformations such as microcephaly.

T cell epitopes from recovered COVID-19 patients identified for vaccine

A new study by researchers at The Hong Kong University of Science and Technology and published on the preprint server bioRxiv in August 2020 collates the available database of SARS-CoV-2 T cell epitopes gathered from 8 studies of COVID-19 patients who recovered. This could serve as a launchpad to fill in knowledge gaps regarding the immunological aspects of this disease, and drive towards an effective T cell vaccine.

Researchers find link between dystrophic muscles and lymphatic system in mice with Duchenne disease

Researchers at the Universities of Maynooth and Bonn discover a new connection in muscular dystrophy Duchenne muscular dystrophy (DMD) is the most common muscle disease in children and is passed on by X-linked recessive inheritance.

Study tracks the mutation rate of SARS-Cov-2 virus

Since COVID-19 began its menacing march across Wuhan, China, in December 2019, and then across the world, the SARS-CoV-2 virus has taken a "whatever works" strategy to ensure its replication and spread.

SARS-CoV-2 a "swarm" of mutant viruses

In this new study, the virus was serially passaged in independent cell types in a controlled environment. The researchers found that the virus rapidly adapts to the changing conditions in culture by selecting for pre-existing species.

Study provides comprehensive update on ACE2 enzyme with key role in SARS-CoV-2 infection

Researchers at Uppsala University have described the presence, throughout the human body, of the enzyme ACE2.

Analysis of the SARS-CoV-2 proteome via visual tools

Now, a new study published on the preprint server bioRxiv* in July 2020 shows how this can be advanced at a greater speed by combining experimental results with homology models obtained by high-throughput pipelines. This will help produce new hypotheses that will show novel druggable targets for effective drug development.
