Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

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.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Modelling the activation of words in human memory : the spreading activation, spooky-activation-at-a-distance and the entanglement models compared [PDF]

, 2011
Modelling how a word is activated in human memory is an important requirement for determining the probability of recall of a word in an extra-list cueing experiment.

Prompt Gamma Activation Analysis at the Budapest Research Reactor

, 2012
Prompt gamma activation analysis is a powerful method, but it is not yet well enough known in the nuclear data community. For this reason, we describe the PGAA measurement and data evaluation processes, as well as the energy and spatial distribution ...

Lysosome activation clears aggregates and enhances quiescent neural stem cell activation during aging

Science, 2018
Lysosomes keep neuronal stem cells young An important consequence of aging is loss of regenerative capacity in stem cells, particularly those of the nervous system. Leeman et al.

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 ...
