By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Generation of cynomolgus monkey capsid-specific positive control cells for IFNγ ELISpot assays for adeno-associated gene therapy applications

Journal of Immunotoxicology
Cell-mediated immune (CMI) responses to adeno-associated virus (AAV) can lead to tissue damage and loss of therapeutic transgene expression. Identifying robust biomarkers and mechanisms of CMI can aid clinical practice and advancement of AAV gene ...

Telomerase Assay Using Biotinylated-Primer Extension and Magnetic Separation of the Products

BioTechniques, 1998
Human telomerase, a ribonucleoprotein enzyme, is known to be associated with immortalized cancer cells but is absent in most normal tissues. Thus, telomerase appears to be an attractive new target for anticancer agents and an important diagnostic marker ...

HBV Core Promoter Inhibition by Tubulin Polymerization Inhibitor (SRI-32007)

Advances in Virology, 2020
Approximately 257 million people chronically infected with hepatitis B virus (HBV) worldwide are at risk of developing hepatocellular carcinoma (HCC). However, despite the availability of potent nucleoside/tide inhibitors, currently there are no curative

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
