Morphological and functional peculiarities of lymphoid cells in mice of different strains

Area of Science:

• Immunology
• Comparative genomics
• Hematology

Background:

• Immune system research often utilizes inbred mouse strains.
• Understanding strain-specific immune responses is crucial for experimental design.
• Quantitative and functional differences in lymphoid cells can impact study outcomes.

Purpose of the Study:

• To investigate variations in lymphoid cell populations and their functional activity among different mouse strains.
• To establish baseline immune profiles for commonly used laboratory mouse strains.

Main Methods:

• Analysis of cellularity and lymphoid element counts in hematopoietic and lymphoid organs.
• Assessment of T lymphocyte and B lymphocyte proliferative activity.
• Quantification of CD4+ and CD8+ T lymphocyte subsets in the spleen.

Main Results:

• CC57W and Balb/c mice showed the lowest cellularity and lymphoid cell counts across organs.
• CBA/CaLac and DBA/2 mice displayed the highest lymphoid cell counts and proliferative activity.
• Balb/c mice had the highest absolute lymphoid cell content in the spleen, while CC57W mice had the highest in the thymus.

Conclusions:

• Significant strain-dependent variations exist in the quantitative composition and functional activity of lymphoid cells.
• These findings highlight the importance of considering mouse strain when interpreting immunological data.
• The identified differences provide a basis for selecting appropriate mouse models in immunological research.
