Positive Selection of TLR2 and MyD88 Genes Provides Insights Into the Molecular Basis of Immunological Adaptation in Amphibians

Ecology and Evolution, Volume 14, Issue 12, December 2024.
We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...

Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

Biological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

Core promoter short tandem repeats as evolutionary switch codes for primate speciation [PDF]

, 2015
Alteration in gene expression levels underlies many of the phenotypic differences across species. Because of their highly mutable nature, proximity to the +1 transcription start site (TSS), and the emerging evidence of functional impact on gene ...

Host and parasite intervality in differentially human‐modified habitats

Oikos, Volume 2024, Issue 12, December 2024.
Host–parasite interactions are influenced by present and past eco‐evolutionary interactions and the local environment. An ecological community defines the potential host range of each parasite and the potential parasite diversity of each host species.

Applications and advancements in animal models for antiviral research on mosquito‐borne arboviruses

Animal Models and Experimental Medicine, Volume 7, Issue 5, Page 673-684, October 2024.
Animal models are crucial in antiviral research on mosquito‐borne arboviruses, playing a role in understanding disease mechanisms, vaccine development, and toxicity testing. The use of animal models confronts hurdles related to ethical considerations and the successful translation of findings from animals to humans.

Where Do Core Thalamocortical Axons Terminate in Mammalian Neocortex When There Is No Cytoarchitecturally Distinct Layer 4?

Journal of Comparative Neurology, Volume 532, Issue 7, July 2024.
Immunohistochemical staining for vesicular glutamate transporter 2 reveals the “core” thalamocortical projection to the neocortex in the African elephant. In the elephant and other mammals with unusual skin (such as pachydermatous skin), layer 4 is cytoarchitecturally indistinct, possibly absent, and the thalamocortical input terminates primarily on ...

Adaptive evolution of the matrix extracellular phosphoglycoprotein in mammals

BMC Evolutionary Biology, 2011
Background Matrix extracellular phosphoglycoprotein (MEPE) belongs to a family of small integrin-binding ligand N-linked glycoproteins (SIBLINGs) that play a key role in skeleton development, particularly in mineralization, phosphate regulation and ...
