简介：
Overview
This protocol outlines a method for isolating quiescent neutrophils from canine blood and quantifying their extracellular trap formation. Neutrophil extracellular traps (NETs) play a significant role in the innate immune response and are linked to various pathologies.
Key Study Components
Area of Science
- Immunology
- Veterinary Medicine
Background
- Neutrophils are key players in the immune response.
- NETs consist of DNA, histones, and proteins released by neutrophils.
- NETs are implicated in autoimmune diseases and thrombosis.
- Understanding NET formation can provide insights into immune responses.
Purpose of Study
- To isolate neutrophils and measure their DNA release in response to various agonists.
- To investigate the neutrophil response to NET-inducing agents.
- To facilitate rapid screening of agonists and inhibitors affecting NET formation.
Methods Used
- Blood samples are collected from a healthy canine donor using a 21-gauge butterfly needle.
- Samples are transferred to EDTA-containing tubes for neutrophil isolation.
- Care is taken to ensure an atraumatic venipuncture for optimal neutrophil yield.
- Inversion of tubes ensures proper mixing of blood and anticoagulant.
Main Results
- The method allows for effective isolation of neutrophils.
- Quantification of NETs can be achieved using a microplate fluorescence assay.
- The protocol supports the investigation of neutrophil responses to various stimuli.
- Rapid screening of NET formation in response to different agonists is possible.
Conclusions
- This protocol provides a reliable method for studying neutrophil behavior.
- Insights gained can contribute to understanding immune responses in both health and disease.
- The technique is beneficial for both research and clinical applications in veterinary medicine.
