Carcinoembryonic Antigen Gene Family [PDF]

, 1991
The carcinoembryonic antigen (CEA) gene family belongs to the immunoglobulin supergene family and can be divided into two main subgroups based on sequence comparisons.

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 ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

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

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

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 ...

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 ...

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 ...
