Tracking Plasma Cell Differentiation in Living Mice with Two-Photon Microscopy

Area of Science:

• Immunology
• Cell Biology

Background:

• Plasma cell differentiation is a complex process occurring within germinal centers.
• Existing in vitro systems do not fully recapitulate the germinal center environment.
• In vivo studies are crucial for understanding plasma cell generation.

Purpose of the Study:

• To describe methods for studying plasma cell generation in vivo.
• To detail the induction of humoral immune responses to model antigens.
• To outline techniques for visualizing and tracking plasma cells and their cellular interactions.

Main Methods:

• Induction of humoral immune responses in mice using defined model antigens.
• In vivo imaging and tracking of plasma cells within lymph nodes.
• Analysis of plasma cell interactions with other immune cells.

Main Results:

• Successful induction of immune responses allowing for plasma cell tracking.
• Visualization of plasma cell behavior and interactions in a native environment.
• Detailed observation of the dynamic processes of plasma cell differentiation.

Conclusions:

• In vivo approaches are essential for dissecting the intricacies of plasma cell generation.
• The described methods provide a robust framework for studying humoral immunity.
• This work facilitates a deeper understanding of the germinal center reaction and plasma cell development.
