Tex19 and Sectm1 concordant molecular phylogenies support co-evolution of both eutherian-specific genes [PDF]

open access: yes, 2015
International audienceBackground: Transposable elements (TE) have attracted much attention since they shape the genome and contribute to species evolution. Organisms have evolved mechanisms to control TE activity. Testis expressed 19 (Tex19) represses TE

Costs and benefits of solitary living in mammals

open access: yesJournal of Zoology, Volume 323, Issue 1, Page 9-18, May 2024.
Seven main factors that influence the social organization of a species. + indicates which condition favours solitary living, − which favours group living. Combined, these factors influence whether solitary or group living leads to a net benefit for females. In mammals, social organization is mainly determined by how females distribute themselves, while

Phylogenetic analysis of 16S mitochondrial DNA data in sloths and anteaters [PDF]

open access: yes, 2003
We sequenced part of the 16S rRNA mitochondrial gene in 17 extant taxa of Pilosa (sloths and anteaters) and used these sequences along with GenBank sequences of both extant and extinct sloths to perform phylogenetic analysis based on parsimony, maximum ...

The discovery of NLRP3 and its function in cryopyrin‐associated periodic syndromes and innate immunity

open access: yesImmunological Reviews, Volume 322, Issue 1, Page 259-282, March 2024.
Summary From studies of individual families to global collaborative efforts, the NLRP3 inflammasome is now recognized to be a key regulator of innate immunity. Activated by a panoply of pathogen‐associated and endogenous triggers, NLRP3 serves as an intracellular sensor that drives carefully coordinated assembly of the inflammasome, and downstream ...
