Ecology and Evolution, Volume 16, Issue 6, June 2026.In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

The CAF1-NOT complex of trypanosomes [PDF]
Frontiers in Genetics, 2014 In African trypanosomes, there is no control of transcription initiation by RNA polymerase II at the level of individual protein-coding genes. Transcription is polycistronic, and individual mRNAs are excised by trans-splicing and polyadenylation. As a consequence, trypanosomes are uniquely reliant on post-transcriptional mechanisms for control of gene ...

Optical trapping reveals propulsion forces, power generation and motility efficiency of the unicellular parasites Trypanosoma brucei brucei [PDF]
, 2014 Unicellular parasites have developed sophisticated swimming mechanisms to survive in a wide range of environments. Cell motility of African trypanosomes, parasites responsible for fatal illness in humans and animals, is crucial both in the insect vector ...

Dynamic disorder is crucial for mitochondrial protein import
Protein Science, Volume 35, Issue 6, June 2026.Abstract The import of proteins into mitochondria poses fundamental mechanistic challenges: aggregation‐prone precursor proteins must be maintained in aqueous compartments and threaded through narrow pores without becoming stuck or mislocalized. Recent evidence from mitochondrial protein import studies and other chaperone systems underscores the ...

A major genetic locus in Trypanosoma brucei is a determinant of host pathology [PDF]
, 2009 The progression and variation of pathology during infections can be due to components from both host or pathogen, and/or the interaction between them. The influence of host genetic variation on disease pathology during infections with trypanosomes has ...

Codon choice directs constitutive mRNA levels in trypanosomes
eLife, 2018 Selective transcription of individual protein coding genes does not occur in trypanosomes and the cellular copy number of each mRNA must be determined post-transcriptionally.

The role of invariant surface glycoprotein 75 in xenobiotic acquisition by African trypanosomes
Microbial Cell, 2023 The surface proteins of parasitic protozoa mediate functions essential to survival within a host, including nutrient accumulation, environmental sensing and immune evasion.

Protein Science, Volume 35, Issue 6, June 2026.Abstract Mitochondrial cristae architecture is central for optimal oxidative phosphorylation and a healthy mitochondrial physiology. The intricate architecture of the inner mitochondrial membrane relies on protein complexes that compartmentalize the membrane by imposing membrane curvature, forming membrane contact sites or membrane subdomains ...

Regulation of Trypanosoma brucei Total and Polysomal mRNA during Development within Its Mammalian Host [PDF]
, 2013 The gene expression of Trypanosoma brucei has been examined extensively in the blood of mammalian hosts and in forms found in the midgut of its arthropod vector, the tsetse fly.
