Exploring the importance of predicted camel NRAP exon 4 for environmental adaptation using a mouse model

Animal Genetics, Volume 56, Issue 1, February 2025.
Abstract Camels possess exceptional adaptability, allowing them to withstand extreme temperatures in desert environments. They conserve water by reducing their metabolic rate and regulating body temperature. The heart of the camel plays a crucial role in this adaptation, with specific genes expressed in cardiac tissue that are essential for mammalian ...

Phosphoantigen recognition by Vγ9Vδ2 T cells

European Journal of Immunology, Volume 54, Issue 11, November 2024.
Binding of microbial or host metabolites (phosphoantigens) to the intracellular Β30.2 domain of butyrophilin (BTN)3A1 (green) initiates binding to B30.2 domains of the BTN2A1 homodimer and results in the formation of a Vγ9Vδ2 TCR ligand which may also include additional components.

Identification of genomic regions associated with differences in fleece type in Huacaya and Suri alpacas (Vicugna pacos). [PDF]

The difference in fleece type is the distinguishing trait between the two types of alpacas (Vicugna pacos), Huacaya and Suri. The Suri fleece type has been found to be inherited dominantly over the Huacaya type, resulting in offspring with the Suri ...

Pastoralism in the high tropical Andes: A review of the effect of grazing intensity on plant diversity and ecosystem services

Applied Vegetation Science, Volume 27, Issue 3, July/September 2024.
The Andes is the most extensive and populated tropical mountain region in the world. Here, pastoralism is a main land use, where two main pastoral systems, camelids in puna and bovines in páramo, impact biodiversity and ecosystem services differently. This literature review analyzes the ecosystem consequences of pastoralism and provides recommendations

Anthelmintic resistance in gastrointestinal nematodes of alpacas (Vicugna pacos) in Australia

Parasites & Vectors, 2018
Background Gastrointestinal nematodes (GINs) can cause significant economic losses in alpacas due to lowered production of fibre and meat. Although no anthelmintics are registered for use in alpacas, various classes of anthelmintics are frequently used ...

Comparative finite element analysis of the first thoracic vertebra in artiodactyls

Journal of Morphology, Volume 285, Issue 5, May 2024.
Using finite element analysis, this study explores the morphology of the first thoracic vertebra (T1) and its performance under compressive and tensile loads in artiodactyls with different neck postures and body sizes. Species with an upright posture exhibited the lowest stress and therefore performed better than species with a suspensory posture under

Biometric description of gestation in the alpaca (Vicugna pacos)

Revista de Investigaciones Veterinarias del Perú, 2023
En el presente estudio se describe la biometría de la gestación de la alpaca (Vicugna pacos). Se determinó el diámetro abdominal en forma mensual de 10 alpacas gestantes. Además, se colectaron 49 úteros grávidos del camal de Maranganí (Cusco, Perú) y fueron clasificados por edad gestacional conocida mediante fecha de empadre (cada 30 días a partir del ...

Characterization of paneth cells in alpacas (Vicugna pacos, Mammalia, Camelidae)

Tissue and Cell, 2016
Paneth cells are secretory epithelial cells of the innate immune system of the intestine of several mammals, including alpacas. Little is known about the latter; thus, in the present study we described the morphology and histochemical characteristics of Paneth cells in healthy fetuses, and young and adult alpacas. For this purpose, samples of duodenum,
