I'm one of the old-timers in this department, judging from
how long I've been a member of the faculty as well as being just old,
now on the threshhold of retirement. I've taught immunology for over a
quarter of a century, and have even learned to teach basic microbiology,
and worse yet, beginning biology. My graduate training took place at the
University of Chicago at a time when immunology was in its infancy (nobody
knew what antibodies really were, and lymphocytes could not possibly have
anything to do with immunity because they looked so quiescent histologically)
and what was really on the minds of many scientists was what ionizing
radiation did to just about anything (remember it was the morning of the
so-called atomic bomb age). Hence I was intellectually raised in the atmosphere
of concern about radiation and immunity. After some time doing this sort
of stuff at the Argonne National Laboratory, and the Radiation Branch
of the National Cancer Institute, everyone seemed to lose interest. But
that experience had implanted deep roots in me, and even today my interest
in the immune system has been rather organismal...the system as a whole,
comprising various interacting organs and tissues. For a while my laboratory
considered the function of the rabbit appendix (about 10 grams of lymphocytes
in one bag!...about 60% of the total lymphoid mass in the rabbit). But
who's interested in rabbits? Now my students and I are breaking new ground
(for us) by inquiring into the contribution of host immune reactivity
to the development of something called periodontal disease, which at its
worst results in tooth loss because the supporting alveolar bone is resorbed.
There is considerable evidence that the inflammatory reactions associated
with the disease (periodontitis) lead to this resorption; our interest
is how the immune reactivity to oral microbes might actually induce the
inflammation and, in effect, ultimately cause the disease. This project
is an offshoot of a broader study of the bacteriology of periodontal disease
artificially-induced in dogs, being carried out by a group of investigators
at this and neighboring campuses. As I write this, we have done most of
the animal and benchwork on a first phase of the study, accumulating reams
of data sheets; now we have to do some serious number crunching to see
if we can learn anything that might give courage to some successor to
pursue the idea further.
I've enjoyed my years here mainly because the department has always maintained
a certain undefineable but pervasive enthusiasm for what we do, a caring
for our students, and a general and genuine good will among us all. As
faculty and students have come and gone that spirit has never seriously
wavered.
