2022: a year in MIS-C research

In a recent review published in Nature Reviews Rheumatology, researchers reviewed existing data on the multisystem inflammatory syndrome in children (or MIS-C).

MALAT1 suppression is a hallmark of tissue and peripheral proliferative T cells in COVID-19

In a recent study posted to the medRxiv* preprint server, researchers in the United Kingdom investigated lncRNA (long non-coding ribonucleic acids) expression in coronavirus disease 2019 (COVID-19) T lymphocyte transcriptomes.

Researchers analyze targets of human T cell recognition against all coronaviruses

Researchers analyzed T cell reactivity against alpha and beta common cold coronaviruses (CoVs) [(CCC)] to inform the development of pan-CoV vaccine concepts.

Research suggests people on rheumatoid arthritis drugs show weaker response to SARS-CoV-2 vaccines

Researchers conducted a comparative study among a cohort of individuals on rheumatoid arthritis (RA) therapies vis-à-vis healthy controls to assess their responses to coronavirus disease 2019 (COVID-19) vaccines.

Is universal coronavirus immunity possible?

In a recent study posted to the bioRxiv* preprint server, researchers at Columbia University characterized reciprocal and non-reciprocal T-cell responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Does the immunization order of vaccine types influence the efficacy of heterologous prime-boost vaccination, especially mRNA and protein-based vaccines?

A new study aimed to analyze whether the order of immunization of vaccine types impacted the efficacy of a heterologous prime-boost vaccination strategy.

Study links epigenetic biological aging and aberrations in neural oscillatory activity in people with HIV

A new research paper was published in Aging (listed as "Aging (Albany NY)" by MEDLINE/PubMed and "Aging-US" by Web of Science) Volume 14, Issue 24, entitled, "Epigenetic aging is associated with aberrant neural oscillatory dynamics serving visuospatial processing in people with HIV."

Free spike proteins in the blood appear to play a role in myocarditis post-COVID mRNA vaccine

A recent study published in the journal Circulation examines the immunological picture in this scenario, looking for clues to the etiology of this rare and potentially serious complication.

Why do some people develop persistent lung sequelae after severe COVID-19?

Clinical presentation following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ranges from mild self-limiting illness to severe respiratory failure. Many studies have analyzed the early acute phases of coronavirus disease 2019(COVID-19), but few focused on the longer-term sequelae following infection.

BA.4/BA.5 mutations reduced responsiveness of epitope-specific T cells with original mRNA vaccine

A new study in the journal Viruses examines the phenomenon of breakthrough infections due to the evasion of T-cell immunity by the Omicron BA.4/BA.5 subvariants, showing this to be due to spike gene mutations.

2 Jan 2023

Underlying genetic cause for MIS-C complications after COVID-19 identified

A recent Science journal study determined the underlying cause of MIS-C related to SARS-CoV-2 in some children. It hypothesized that monogenic inborn errors of immunity (IEI) is the primary reason for this condition. Identifying these inborn errors is expected to help elucidate the disease's cellular, molecular, and immunological basis.

Exploring T cell responses during COVID-19 breakthrough infection

Researchers assessed the de novo and recall T cell responses during coronavirus disease 2019 (COVID-19) breakthrough infection.

28 Dec 2022

T-cell immunity remains effective against SARS-CoV-2 Omicron subvariants

Omicron subvariants effectively escape B-cell immune responses by modifying neutralizing antibody epitopes.

21 Dec 2022

The implications of pulmonary tissue-resident memory T lymphocytes in COVID-19 and other respiratory diseases

Researchers elucidated the mechanisms of long-term T lymphocyte lodgement in tissues other than lymphoid tissues and the reasons for the transient residency of specific subsets of tissue-resident memory T (TRM) lymphocytes.

14 Dec 2022

Researchers identify molecular determinants of post-infection long-COVID

In a recent study published in the journal Nature Medicine, researchers presented a transcriptome-wide assessment of blood gene expression changes that occur in acute COVID-19 (coronavirus disease 2019) and are associated with PASC (post-acute sequelae of COVID-19), commonly known as long-COVID.

13 Dec 2022

Study suggests persistent inflammatory response triggered by SARS-CoV-2 may be responsible for observed sequelae in PASC patients

Researchers assessed the association of enhanced migratory or activated CD8+ T cell and reduced avidity reactive cellular response due to post-acute COVID-19 syndrome (PASC).
