Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

What determines host specificity in hyperspecialized plant parasitic nematodes?
BMC Genomics, 2019 Background In hyperspecialized parasites, the ability to grow on a particular host relies on specific virulence factors called effectors. These excreted proteins are involved in the molecular mechanisms of parasitism and distinguish virulent pathogens ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Host Specificity in Raiding Behavior of the Slave-Making Ant Polyergus Lucidus
Psyche: A Journal of Entomology, 1987 In the pine barrens of Suffolk County, New York, at least three species of Formica (subgenus Neoformica) are used as slaves by the obligatory slave-making ant Polyergus lucidus. In any single nest, however, only one slave species may be found.

Within‐community variation of interspecific divergence patterns in passerine gut microbiota
Ecology and Evolution, 2022 Gut microbiota (GM) often exhibit variation between different host species and co‐divergence with hosts' phylogeny. Identifying these patterns is a key for understanding the mechanisms that shaped symbiosis between GM and its hosts.

Multi-host Bartonella parasites display covert host-specificity even when transmitted by generalist vectors. [PDF]
, 2016 Many parasites infect multiple sympatric host species and there is a general assumption that parasite transmission between co-occurring host species is commonplace.

Molecular Oncology, EarlyView.This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

Odour perception in the codling moth Cydia pomonella L. [PDF]
, 2004 The codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae) is a renowned pest in apple, pear and walnut orchards, and its activities are in large guided by volatile odours as sensory cues.

Molecular Oncology, EarlyView.This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...
