Linking Microbiome Diversity and Immune Profiles in Ethiopian Patients With Cervical Cancer

JCO Global Oncology
PURPOSEThis study investigates the interplay between T-cell receptor (TCR) immune characteristics and microbiome profiles to explore the relationship between immune diversity and microbial composition in cervical samples from Ethiopia.METHODSCervical ...

Enhancement of immune checkpoint inhibitor efficacy by DHX58+ SELL+ T cells in advanced gastric cancer

VIEW, EarlyView.
We created a coculture system using patient‐derived organoids (PDOs) and tumor‐infiltrating lymphocytes (TILs) that mimics important interactions between PDOs and TILs in the presence of various ICIs. Our findings reveal that CD62L+ T cells, activated by CD44+ cancer stem cells (CSCs), facilitate tumor regression in samples sensitive to ICIs, which is ...

TCR Bias and Affinity Define Two Compartments of the CD1b- Glycolipid-Specific T Cell Repertoire

, 2014
Current views emphasize TCR diversity as a key feature that differentiates the group 1 (CD1a, CD1b, CD1c) and group 2 (CD1d) CD1 systems. Whereas TCR sequence motifs define CD1d-reactive NKT cells, the available data do not allow a TCR-based organization

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

VIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Activation of the Hedgehog signaling pathway in T-lineage cells inhibits TCR repertoire selection in the thymus and peripheral T-cell activation

, 2007
TCR signal strength is involved in many cell fate decisions in the T-cell lineage. Here, we show that transcriptional events induced by Hedgehog (Hh) signaling reduced TCR signal strength in mice.

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

VIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...

Analysis of the TCR Repertoire in HIV-Exposed but Uninfected Infants

Scientific Reports, 2019
AbstractMaternal human immunodeficiency virus (HIV) infection has been shown to leave profound and lasting impacts on the HIV-exposed uninfected (HEU) infant, including increased mortality and morbidity, immunological changes, and developmental delays compared to their HIV-unexposed (HU) counterparts.

Early Epidemiologic and Immune Predictors of Atopic Dermatitis: Reduced Cord Blood Regulatory B10 Cells in the Munich Atopy Prediction Study (MAPS)

Allergy, EarlyView.
In this prospective birth cohort from Munich, comprehensive clinical assessments and longitudinal lifestyle questionnaires were combined with cord blood immune profiling. Infants who later developed AD showed altered cord blood immune signatures, including reduced CD4+ T cells, increased B cells and markedly decreased Breg cells. Epidemiologic factors,

Escaping high viral load exhaustion: CD8 cells with altered tetramer binding in chronic hepatitis B virus infection

, 2002
Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in

MAIT Cells Suppress IgE‐Mediated Asthma via IFNγ‐Dependent B Cell Regulation

Allergy, EarlyView.
In this study, we demonstrate that MAIT cell antagonism during sensitization and challenge with HDM worsens the development of airway hyperreactivity without effects on type 2 or 17 associated cytokine production or lung inflammation. Rather, MAIT cells appear to regulate HDM‐induced asthma through direct inhibition of IgE production.
