Selection, transmission, and reversion of an antigen-processing cytotoxic T-lymphocyte escape mutation in Human Immunodeficiency Virus Type 1 infection [PDF]

, 2004
Numerous studies now support that human immunodeficiency virus type 1 (HIV-1) evolution is influenced by immune selection pressure, with population studies showing an association between specific HLA alleles and mutations within defined cytotoxic T ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

The ubiquitin-like modifier FAT10 is not essential for MHC-I antigen presentation

Frontiers in Immunology
IntroductionThe presentation of pathogen-derived antigens on major histocompatibility complex (MHC) class I is crucial for the antiviral immune response. Degradation of intracellular pathogen-derived proteins by the 26S proteasome generates peptides that

Estimation of endoplasmic reticulum aminopeptidase 1 level of expression in lesional and nonlesional skin of psoriatic patients and healthy controls

Journal of the Egyptian Women’s Dermatologic Society, 2021
Background Psoriasis is a chronic inflammatory autoimmune disease of the skin, in which an elevated expression of endoplasmic reticulum aminopeptidase 1 (ERAP1), an enzyme involved in the final processing of major histocompatibility complex-I ligands ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Antigen Processing and Presentation in Multiple Sclerosis

, 2009
CD4(+) T cells play a central role in the pathogenesis of multiple sclerosis (MS). Generation, activation and effector function of these cells crucially depends on their interaction with MHC II-peptide complexes displayed by antigen presenting cells (APC)

Conformational bias in SARS-CoV-2 Spike CD4+ T-cell epitope dominance

Frontiers in Immunology
IntroductionEpitope-specific T cells provide significant long-lived protection afforded by adaptive immunity to SARS-CoV-2 spike. CD4+ T-cell epitope peptides that are generated by non-ATP-dependent antigen-processing proteases bind with modest ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Phosphorylation shapes antigen presentation and immune recognition: mechanistic insights and translational perspectives

Frontiers in Immunology
Phosphorylation is a reversible post-translational modification that dynamically regulates immune responses by reshaping the antigen profiles. Phosphoproteomics and immunopeptidomics studies reveal that phosphorylated peptides (phosphopeptides) are ...
