[Cloning and tissue distribution analysis of CD1d in Rhesus macaque].

Area of Science:

• Immunology
• Molecular Biology

Context:

• CD1d is a crucial molecule in the immune system, presenting lipid antigens to T cells.
• Natural Killer T (NKT) cells, which recognize CD1d-lipid complexes, play significant roles in immune responses.
• Understanding CD1d expression is vital for studying NKT cell function in various species.

Purpose:

• To amplify the CD1d gene from Rhesus macaque tissues.
• To determine the tissue-specific expression profile of CD1d mRNA in Rhesus macaques.

Summary:

• Total RNA was extracted from various Rhesus macaque tissues.
• CD1d was amplified using specific primers and its expression analyzed via semi-quantitative RT-PCR with GAPDH as a control.
• Highest CD1d expression was observed in the heart, liver, and spleen, with lower levels in blood, lung, small intestine, and stomach, and minimal expression in the brain.

Impact:

• Successful CD1d amplification enables the production of anti-CD1d antibodies and CD1d-tetramers for NKT cell research in Rhesus macaques.
• The established CD1d expression profile aligns with known NKT cell functions in other species.
• These findings provide a foundation for investigating the role of CD1d/NKT cells in Rhesus macaque physiology and disease.
