Type II collagen-reactive T cell clones from mice with collagen-induced arthritis

Certain strains of mice develop a symmetrical polyarthritis after immunization with type II collagen. The incidence of arthritis after such immunization is variable. To study the arthritogenic potential of T cells reactive with type II collagen, we isolated draining lymph node cells from mice that had developed arthritis after immunization with bovine type II collagen. From these immune lymph node cells we were able to clone T cells reactive with type II collagen. Two separate sets of T cell clones were isolated. The first set reacted with either native bovine or native chick type II collagen, but did not react with type I collagen. The second set of T cell clones reacted with bovine type II collagen, but did not respond to either native chick type II collagen or type I collagen. These clones will be tested for their influence on the development of arthritis in vivo.
