Single cell and immunity: Better understanding immune cell heterogeneities with single cell sequencing

Single-cell sequencing has scientific impacts on better understanding the immunity. There is a rapid development in single cell-based databases and analytic tools to provide the potential of clinical and translational discovery. The understanding of single-cell based immunity needs a strong program and solid evidence of preclinical and clinical validation and evaluation. The current special topic issue on single cell and immunity aimed to provide a strong communication for the progress of single cell-based studies on immune cell functional diversity in development and disease. The topic has a clear scope on the application of single cell sequencing to better understand immune cell heterogeneities, functions, cell-cell interactions, responses and regulatory roles in systems immunology and diseases.
