Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Machine learning enhanced immunologic risk assessments for solid organ transplantation

Scientific Reports
The purpose of this study was to enhance the prediction of solid-organ recipient and donor crossmatch compatibility by applying machine learning (ML). Prediction of crossmatch compatibility is complex and requires an understanding of the recipient and ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Role of donor-specific antibodies in immunological assessment for kidney transplant: A report of ten cases in a cost-limited set-up

Indian Journal of Transplantation, 2020
Sensitized patients, who constitute a considerable proportion of kidney-transplant recipients, often have poor allograft outcomes. Only cell-based complement-dependent cytotoxicity (CDC) assays are typically used to quantify donor-specific antibodies ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The impact of HLA donor-specific antibodies on engraftment and the evolving desensitization strategies.

, 2022
The majority of contemporary allogeneic hematopoietic stem cell transplantation (HCT) procedures utilize partially HLA-mismatched stem cell grafts. Donor-specific anti-HLA antibodies (DSA) are associated with primary graft failure independent of the ...

Utility of Routine Post Kidney Transplant Anti-HLA Antibody Screening

Kidney International Reports
Introduction: De novo donor-specific antibody (dnDSA) is a strong biomarker associated with the development of antibody-mediated rejection (AMR) and graft loss after kidney transplantation.

Desensitization with plasma exchange in a patient with human leukocyte antigen donor-specific antibodies before T-cell-replete haploidentical hematopoietic stem cell transplantation

Journal of Applied Hematology, 2019
The presence of human leukocyte antigen (HLA) donor-specific antibodies (DSAs) increases the risk of graft failure in T-cell-replete haploidentical hematopoietic stem cell transplantation (haploidentical-HSCT). We report a case of a 20-year-old male with

Prospecting the protein design landscape

FEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
