Advances in Single-Cell Transcriptomics for Livestock Health.

Area of Science:

• Livestock genomics and immunology
• Single-cell transcriptomics applications

Background:

• Single-cell RNA sequencing (scRNA-seq) offers deep insights into cellular diversity and immune responses in livestock.
• Existing research highlights the need for comprehensive cellular atlases in farm animals.

Purpose of the Study:

• To review recent advances in applying single-cell transcriptomics to livestock health.
• To focus on immune system organization and host-pathogen interactions in key livestock species.
• To assess technical challenges and future directions in the field.

Main Methods:

• Review of recent scientific literature on single-cell transcriptomics in livestock.
• Analysis of large-scale cell atlases (e.g., Cattle Cell Atlas, FarmGTEx).
• Examination of single-cell immune receptor sequencing data.

Main Results:

• Identification of tissue- and species-specific immune cell populations.
• Clarification of pathogen cellular tropism and immune evasion strategies.
• Discovery of unique immunological features, such as the role of γδ T cells in ruminants.
• Advancement in monoclonal antibody discovery and vaccine design.

Conclusions:

• Single-cell transcriptomics provides a powerful framework for understanding livestock immunity.
• Overcoming technical challenges is crucial for further progress.
• Integrating spatial transcriptomics and multi-omics will enhance future research for improved livestock health and disease resistance.
