Cutaneous Leishmaniasis: The Complexity of Host’s Effective Immune Response against a Polymorphic Parasitic Disease

open access: yesJournal of Immunology Research, Volume 2019, Issue 1, 2019., 2019
This review is aimed at providing a comprehensive outline of the immune response displayed against cutaneous leishmaniasis (CL), the more common zoonotic infection caused by protozoan parasites of the genus Leishmania. Although of polymorphic clinical presentation, classically CL is characterized by leishmaniotic lesions on the face and extremities of ...

Adaptation and Constraint in the Atypical Chemokine Receptor Family in Mammals

open access: yesBioMed Research International, Volume 2018, Issue 1, 2018., 2018
Atypical chemokine receptors (ACKRs) are a subclass of G protein‐coupled receptors characterized by promiscuity of ligand binding and an obvious inability to signal after ligand binding. Although some discoveries regarding this family in Homo sapiens and other species have been reported in some studies, the evolution and function of multiple ACKR in ...

Convergence of gut microbiomes in myrmecophagous mammals

open access: yesMolecular Ecology, Volume 23, Issue 6, Page 1301-1317, March 2014., 2014
Abstract Mammals have diversified into many dietary niches. Specialized myrmecophagous (ant‐ and termite‐eating) placental mammals represent a textbook example of evolutionary convergence driven by extreme diet specialization. Armadillos, anteaters, aardvarks, pangolins and aardwolves thus provide a model system for understanding the potential role of ...

Anthropogenic extinctions explain most size and trophic mismatches between large mammalian primary consumers from Amazonian and African rainforests

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
Present‐day Amazonia has an impoverished fauna of large folivorous mammals by comparison with African rainforests, but recent fossil discoveries suggest that late‐Quaternary anthropogenic extinctions could account for most size and trophic faunal mismatches.
