The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis
Journal of Periodontal Research, EarlyView.Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Exploring the diversity of AVPR2 in Primates and its evolutionary implications
Genetics and Molecular Biology, 2023 The current study focuses on the investigation of AVPR2 (VTR2C) protein-coupled receptor variants specific to different primate taxa. AVPR2 is activated by the neurohormone AVP, which modulates physiological processes, including water homeostasis.

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques
Advanced Science, Volume 13, Issue 14, 9 March 2026.Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

American Journal of Primatology, Volume 88, Issue 1, January 2026.Genetic analyses of an allochthonous population of Leontopithecus, illegally introduced into an area of the Brazilian Atlantic Forest in Rio de Janeiro, did not detect signs of hybridization. This data provides crucial information to support conservation efforts and prevent new threats to the endangered lion tamarins. ABSTRACT Allochthonous species can

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae)
American Journal of Primatology, Volume 88, Issue 1, January 2026.Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Guidelines and considerations for capturing and collaring wild primates: a case study with capuchin monkeys (Sapajus nigritus cucullatus) [PDF]
Anais da Academia Brasileira de CiênciasMany aspects of the ecology, evolution and social behavior of wild-living primates remain un-explored and require further investigation. While long-term field studies are crucial for addressing conservation concerns for many primates’ species, acquiring ...

Ecology and Evolution, Volume 15, Issue 11, November 2025.Our study investigated the microbiomes of suprapubic and sternal scent glands in two wild tamarin species to explore their putative roles in odor production and communication. Using metagenomic sequencing, we identified 18 odor‐associated microbial taxa and 26 related metabolic pathways, finding significant differences in microbial diversity and ...
