CAARE Citizens for
Alternatives to Animal Research
October 2018
An esteemed Professor of Microbiology and Immunology at Stanford University School of Medicine is issuing a bold call for human immunology research that focuses on studying human patients, as opposed to artificially induced diseases in animals.

He bases his conclusion on years of seeing diseases cured in mice, while
corresponding progress in human disease has been lacking.
Dr. Davis, who directs the Stanford Institute for Immunology,
Transplantation and Infection, studies how the immune system’s T-cells (a
type of white blood cell) recognize and attack antigens, which are the
specific proteins found on the surfaces of invading viruses, bacteria, and
cancer cells.
Using blood and tissue samples from patients, he employs a process known as
mass cytometry, which can flag antibodies within the cell, combined with
computational methods to examine the larger workings of the immune system.

A maladaptive immune system can trigger autoimmune diseases by wrongly
attacking different parts of the body. This has critical applications for a
wide range of autoimmune diseases like multiple sclerosis and type 1
diabetes, for which, as Dr. Davis points out, we’ve had copious cures in
mice but none in humans.
The Davis lab focuses on exploring immunology as a whole organ system that
includes genetic and environmental effects, which are studied by gene
analysis of twins or regional human populations.

Such crucial work is impossible using mice. “The mouse is a different
species that has developed an immune system meant to deal with completely
different types of infections,” he points out.
Dr. Davis observes that immunology research on mice would be considered
illegal and immoral in humans. For example, to study multiple sclerosis,
which does not occur in mice, scientists must induce a nervous system
disorder.
They do this by injecting mice with diseased spinal cord extracts or
neurotoxins to cause brain inflammation. The result is prolonged and extreme
suffering, marked by progressive whole-body deterioration, spasms,
difficulty breathing, paralysis and ultimately death.
