Effects of orexins on 17β-estradiol synthesis and P450 aromatase modulation in the testis of alpaca (Vicugna pacos). [PDF]

, 2018
The steroidogenic enzyme P450 aromatase (ARO) has a key role in the conversion of testosterone (T) into estrogens (E), expressed as 17β-estradiol. The presence and localization of this key enzyme have not been described before in the South American ...

Alpaca (Vicugna pacos), the first nonprimate species with a phosphoantigen-reactive Vγ9Vδ2 T cell subset

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Human Vγ9Vδ2 T cells are important mediators of immunosurveillance and targets for cell-based immunotherapy. Activation by small molecular compounds called phosphoantigens is essential for their functions and involvement of butyrophilins ...

Calcinosis in Alpaca Crias (Vicugna pacos) Due to Vitamin D Intoxication—Clinical, Laboratory and Pathological Findings with a Focus on Kidney Function

Animals, 2021
Simple Summary Alpacas in central Europe often suffer from vitamin D deficiency due to lower UV radiation. Many alpacas are therefore additionally treated with vitamin D3.

Role of microRNA508-3p in melanogenesis by targeting microphthalmia transcription factor in melanocytes of alpaca

Animal, 2017
It has been demonstrated that microRNAs (miRNAs) play important roles in the control of melanogenesis and hair color in mammals. By comparing miRNA expression profiles between brown and white alpaca skin, we previously identified miR508-3p as a ...

Landscape of variable domain of heavy‐chain‐only antibody repertoire from alpaca

Immunology, 2020
Heavy‐chain‐only antibodies (HCAbs), which are devoid of light chains, have been found naturally occurring in various species including camelids and cartilaginous fish. Because of their high thermostability, refoldability and capacity for cell permeation,
