Wolbachia Promotes Its Own Uptake by Host CellsL. B. Nevalainen, E. M. Layton and I. L. G. Newton, Infection and Immunity, e0055722. 2023.
Wolbachia pipientis is an incredibly widespread bacterial symbiont of insects, present in an estimated 25 to 52% of species worldwide. Wolbachia is faithfully maternally transmitted both in a laboratory setting and in the wild. In an established infection, Wolbachia is primarily ... |

Wolbachia RNase HI contributes to virus blocking in the mosquito Aedes aegyptiM. Hussain, G. Zhang, M. Leitner, L. M. Hedges and S. Asgari, iScience, 26:105836. 2023.
The endosymbiotic bacterium Wolbachia pipientis blocks replication of several arboviruses in transinfected Aedes aegypti mosquitoes. However, the mechanism of virus blocking remains poorly understood. Here, we characterized an RNase HI gene from Wolbachia, which is rapidly ... |

Bypassing Mendel’s First Law: Transmission Ratio Distortion in MammalsG. Friocourt, A. Perrin, P. A. Saunders, E. Nikalayevich, C. Voisset, C. Coutton, G. Martinez and F. Morel, International Journal Molecular Sciences, 24. 2023.
Mendel's law of segregation states that the two alleles at a diploid locus should be transmitted equally to the progeny. A genetic segregation distortion, also referred to as transmission ratio distortion (TRD), is a statistically significant deviation from this rule. TRD has ... |
