Structural and Functional Analysis of the Costimulatory Receptor Programmed Death-1 [PDF]

open access: yesImmunity, 2004
PD-1, a member of the CD28/CTLA-4/ICOS costimulatory receptor family, delivers negative signals that have profound effects on T and B cell immunity. The 2.0 A crystal structure of the extracellular domain of murine PD-1 reveals an Ig V-type topology with overall similarity to the CTLA-4 monomer; however, there are notable differences in regions ...

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Yeast Bax Inhibitor, Bxi1p, Is an ER-Localized Protein that Links the Unfolded Protein Response and Programmed Cell Death in \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e [PDF]

open access: yes, 2011
Bax inhibitor-1 (BI-1) is an anti-apoptotic gene whose expression is upregulated in a wide range of human cancers. Studies in both mammalian and plant cells suggest that the BI-1 protein resides in the endoplasmic reticulum and is involved in the ...

Exceptional Response with Immunotherapy in a Patient with Anaplastic Thyroid Cancer [PDF]

open access: yes, 2017
Chemotherapy with or without radiation is the standard therapy for anaplastic thyroid cancer (ATC), although the response rate is not high and not durable.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Moving forward to address key unanswered questions on targeting PD-1/PD-L1 in cancer: limitations in preclinical models and the need to incorporate human modifying factors. [PDF]

open access: yes, 2019
The tremendous clinical success of immune checkpoint inhibition (ICI), particularly targeting the programmed cell death protein 1 (PD-1)/programmed death-ligand 1/2 (PD-L1/2) pathway, has resulted in application to multiple cancers, as a monotherapy and ...

Sphingosine Phosphate Lyase Expression Is Essential for Normal Development in Caenorhabditis elegans [PDF]

open access: yes, 2003
Sphingolipids are ubiquitous membrane constituents whose metabolites function as signaling molecules in eukaryotic cells. Sphingosine 1-phosphate, a key sphingolipid second messenger, regulates proliferation, motility, invasiveness, and programmed cell ...

Regulation of Postsurgical Fibrosis by the Programmed Death-1 Inhibitory Pathway [PDF]

open access: yesThe Journal of Immunology, 2004
Abstract Surgical adhesions are a common and often severe complication of abdominal or pelvic injury that cause pelvic pain, bowel obstruction, and infertility in women. Current treatments are of limited effectiveness because little is known about the cellular and subcellular processes underlying adhesiogenesis.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Breast cancer immunology and immunotherapy: targeting the programmed cell death protein-1/programmed cell death protein ligand-1

open access: yesChinese Medical Journal, 2020
. Historically, breast cancer has been regarded as an immunogenic “cold” tumor. However, the discovery of immune checkpoint inhibitors has made immunotherapy becoming an emerging new treatment modality for breast cancer.
