Lack of protective effect of autotransplanted splenic tissue to
pneumococcal challenge
AD Schwartz, JF Goldthorn, JA Winkelstein and AJ Swift
Studies in animals and clinical experience in patients have demonstrated
that splenectomy may lead to an increased susceptibility to infection. The
infections are usually caused by encapsulated bacteria such as
penumococcus. It has been shown in a variety of experimental animals that
autotransplanted splenic tissue is capable of regenerating into implants
that are microscopically indistinguishable from normal spleen and of
restoring a number of normal splenic functions. The response to intravenous
challenge with Streptococcus pneumoniae, type 25, was therefore studied in
control, asplenic, and autotransplanted Sprague-Dawley rats. Despite
previous observations that a number of immune functions can be restored in
this animal model by autotransplanted splenic tissue, the present study
indicates that splenic tissue autotransplants do not restore the ability to
resist intravenous pneumococcal challenge.
