Signal Transducer and Activator of Transcription (STAT) Proteins Regulate Mucosal‐Associated Invariant T (MAIT) Cell Function

Immunology, EarlyView.
Integrated transcriptomic, proteomic and flow cytometry analyses reveal that STAT1 negatively regulates MAIT cell effector and glycolytic functions, while STAT3, STAT5 and HIF1α act as positive modulators. Targeting these pathways may offer new strategies to restore MAIT cell function in immune dysregulation and cancer.

Activation of the Lectin Pathway Drives Persistent Complement Dysregulation in Long COVID

Immunology, EarlyView.
The complement cascade, a series of blood proteins that assists in the recognition and neutralisation of pathogens, either independently or in conjunction with antibodies, is persistently activated in patients with long COVID. We found that blood plasma samples from patients with long COVID contained elevated concentrations of the mannan‐binding lectin‐

Latent Neoehrlichia mikurensis Infections May Be Reactivated in Patients With B‐Cell Lymphomas Treated With Rituximab

Immunology, EarlyView.
Eight percent of this cohort of patients had a latent Neoehrlichia mikurensis infection. It was only the latently infected patients who had N. mikurensis‐specific T cells, not the matched B‐cell lymphoma patients without the infection. The T‐cell responses of latently infected patients included perforin‐expressing Th1 and CD8+ T cells that upregulated ...

Unraveling A‐β+ ketosis‐prone diabetes: An evolving diagnosis with an elusive pathogenesis

Journal of Diabetes Investigation, EarlyView.
ABSTRACT Since the discovery of insulin over a century ago, how we conceptualize, describe and treat diabetes has evolved, paving the way for the identification of distinct diabetes subgroups and individualized treatment options. Historically, the term ketosis‐prone diabetes (KPD) has comprised a group of diabetes syndromes characterized by severe ...
