The
Advanoc
iln
PSP
Researoh
ln
this
study, we find
that
PSP
can enhance
the proliferation
of LAK
cells
and
their eliminating
actions on
cancer
cells.
We
also
discover that
immunosuppressive factors
can
hinder the activity
of
LAK cells. but
Polysaccharide Peptide (PSP)
is
capable
of
counteracting the inhibitory
eff6cts of immunosuppressive factors on LAK
cells.
This
suggests that
it is
significant to substitute
paftially or
even
completely,
PSP
for
interleukin-2
utilizing LAK cells to
treat
cancer patients.
