The deer model is an important biomedical research tool, widely used to study human diseases and biological mechanisms. Its biological characteristics and similar physiological responses to humans make it an ideal experimental animal, especially for drug development and disease modeling.

First, the deer model shows significant advantages in studying immune system and metabolic diseases. Deer's immune system is similar to that of humans, making it an important choice for research into autoimmune diseases, infectious diseases, and vaccine development. At the same time, the metabolic characteristics of deer also provide a good platform for the study of metabolic diseases such as diabetes and obesity. These characteristics allow researchers to obtain pathological features similar to human diseases on a relatively small scale, allowing them to test treatments more effectively.

Secondly, deer models also play an important role in ecology and evolutionary biology research. Because of deer's sensitivity to environmental changes, researchers can assess the health of ecosystems by observing deer behavior and physiological responses. By studying deer population dynamics, for example, scientists are able to predict the effects of habitat change and develop conservation strategies to protect these species and their habitats.

In addition, deer models are also of great significance in toxicology studies. Through exposure responses to deer, researchers can assess the potential harm to organisms from various chemicals. This is of great practical significance for the protection of ecological environment and human health.

In the future, with the development of gene editing technology, the research of deer models is expected to be further deepened. Scientists can use genetic modifications to create specific pathological models, which will help to better understand disease mechanisms as well as develop new treatment options.
