简介：
Overview
This article describes a reliable diet-induced rodent model for nonalcoholic steatohepatitis (NASH) achieved through non-SPF housing and a specific high-fat diet. It focuses on identifying immune cell subsets in hepatic and adipose tissues to mirror human immunological conditions.
Key Study Components
Area of Science

What is NASH?
Nonalcoholic steatohepatitis (NASH) is a liver condition characterized by inflammation and fat accumulation not due to alcohol consumption.
How does the rodent model help in research?
Rodent models mimic human metabolic conditions, allowing researchers to study disease mechanisms and potential treatments.
What is the significance of immune cells in obesity?
Immune cells play a crucial role in inflammation associated with obesity, influencing metabolic health and disease progression.
What techniques are used for cell isolation?
Techniques include enzymatic digestion and mechanical dissociation to obtain viable immune cells from tissues.
Why is flow cytometry important?
Flow cytometry allows for the detailed analysis of immune cell populations, providing insights into their functions and roles in disease.
