Article Synopsis
  • - Long-COVID (LC) is defined by lingering symptoms for over 3 months post-COVID-19 infection, potentially caused by immune system dysregulation and chronic inflammation.
  • - The study identifies specific CD4 T cell subpopulations in COVID-19 recovery and reveals that certain CCR6-expressing T cells are reduced in LC patients, while others increase.
  • - LC patients demonstrate lower levels of IFN-γ-secreting CD8 T cells when exposed to the SARS-CoV-2 Spike protein, highlighting the importance of CCR6 in understanding LC's underlying mechanisms.

Article Synopsis
  • A study evaluated the immune response of rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients to COVID-19 vaccines after stopping methotrexate (MTX) treatment for 1 or 2 weeks compared to those who continued MTX.
  • Patients who paused MTX showed higher levels of antibodies and a stronger T-cell response, particularly in the group that withdrew for 2 weeks.
  • Importantly, stopping MTX did not lead to increased flare-ups of RA or PsA, suggesting that a temporary withdrawal could enhance vaccine effectiveness without risking disease stability.

Management of eosinophil-associated inflammatory diseases: the importance of a multidisciplinary approach.

Front Immunol

June 2023

Centro de Investigación Biomédica en Red de Enfermedades Respiratorias (CIBERES), Madrid, Spain.

Elevated eosinophil counts in blood and tissue are a feature of many pathological processes. Eosinophils can migrate and accumulate in a wide variety of tissues and, by infiltrating a target organ, can mediate the development of several inflammatory diseases. The normalization of eosinophilia is a common biomarker of a treatable trait and can also be used as a prognostic and predictive biomarker since it implies a reduction in type 2 inflammation that contributes to disease pathogenesis.

Sec22b-dependent antigen cross-presentation is a significant contributor of T cell priming during infection with the parasite .

Front Cell Dev Biol

March 2023

Instituto de Inmunología Clínica y Experimental de Rosario (IDICER), CONICET, Universidad Nacional de Rosario, Rosario, Argentina.

Antigen cross-presentation is a vital mechanism of dendritic cells and other antigen presenting cells to orchestrate the priming of cytotoxic responses towards killing of infected or cancer cells. In this process, exogenous antigens are internalized by dendritic cells, processed, loaded onto MHC class I molecules and presented to CD8 T cells to activate them. Sec22b is an ER-Golgi Intermediate Compartment resident SNARE protein that, in partnership with sintaxin4, coordinates the recruitment of the transporter associated with antigen processing protein and the peptide loading complex to phagosomes, where antigenic peptides that have been proteolyzed in the cytosol are loaded in MHC class I molecules and transported to the cell membrane.

  • PLK1 is an essential kinase involved in mitosis, but its role in male meiosis has not been fully investigated.
  • Inhibiting PLK1 with BI 2536 in seminiferous tubules revealed that it disrupts the disassembly of key proteins during the meiotic phase called diakinesis, and affects their normal recruitment during prometaphase I.
  • The study indicates that PLK1 is a crucial regulator of the transition from late prophase I to metaphase I in mouse spermatocytes, influencing important recruitment pathways for other proteins involved in meiosis.
