Summary
Mink serum causes rapid death in mice due to high complement activity, especially the alternative pathway. Reducing complement activity, not just antibodies, prevents this toxicity.
Area of Science:
- Immunology
- Complement System Biology
Context:
- Mink serum administration to mice resulted in rapid mortality.
- The underlying mechanism of this toxicity was investigated.
Purpose:
- To elucidate the mechanism behind the toxicity of parenteral mink serum in mice.
- To determine the role of complement activation and antibodies in this phenomenon.
Summary:
- High complement activity in mink serum, particularly the alternative pathway, is responsible for rapid mouse death.
- While antibodies to mouse erythrocytes are involved in lysis, their removal did not abolish toxicity.
- Partial decomplementization of mink serum using zymosan prevented mortality, indicating complement's central role.
Impact:
- Identifies the complement system as the primary driver of mink serum toxicity in mice.
- Suggests therapeutic strategies targeting complement activation to mitigate adverse reactions to foreign sera.
