Abstract:
This chapter presents a series of quantitative analyses that can be used to study the formation of the immune synapse (IS) in B cells. The methods described are automated, consistent, and compatible with open-source platforms. The IS is a crucial structure involved in B cell activation and function, and the spatiotemporal organization of this structure is analyzed to provide a better understanding of its mechanisms. The analyses presented here can be applied to other immune cells and are accessible to researchers of diverse fields. In addition, the raw data derived from the results can be further explored to perform quantitative measurements of protein recruitment and tracking of intracellular vesicles. These techniques have the potential to enhance not only our understanding of the IS in B cells but also in other cell models.
