The KTCC was founded in 1991 to provide an opportunity for
researchers in Japan working on T cells and related fields to
exchange scientific ideas through intensive discussions. The KTCC
puts the highest value on the discussions based on the work and
thoughts of each group. Since such an opportunity has hardly been
encountered in Japan until recently, the organizers are still looking
for a better arrangement of the meeting. Any problem pointed out by
participants will be considered for the next meeting.

It is our great pleasure to be able to invite foreign researchers
from a variety of countries. However, because there are many
difficulties for most Japanese researchers to have a hot discussion
in English, we have decided to divide the meeting into Part I (oral
presentation and discussion in Japanese) and Part II (symposium in
English). To provide an opportunity for all participants to freely
communicate with each other, poster sessions have been arranged in
the evenings of October 14 and 15, where all oral presentations are
displayed as posters in English.

lymphocytes stimulated by McAb OKT3 depends on the presence of IL-2
or autologous adherent bone marrow cells and the expression of HLA-DR
antigen.
