Neuronal plasminogen activators: cell surface binding sites and involvement in neurite outgrowth
RN Pittman, JK Ivins and HM Buettner
Department of Pharmacology, University of Pennsylvania School of Medicine, Philadelphia 19104.
Sympathetic neurons release both urokinase plasminogen activator (uPA) and
tissue plasminogen activator (tPA). A number of inhibitors of serine
proteases have been tested to determine their effects on neurite outgrowth
from rat sympathetic neurons. Some inhibitors increase neurite outgrowth
while others have little or no effect on outgrowth. Inhibition of
plasminogen activator (PA) activity but not other serine protease activity
correlates with the increase in neurite outgrowth (uPA, r = 0.89; tPA, r =
0.86; plasmin, r = 0.015; thrombin, r = 0.025). Antibodies that inhibit uPA
activity increase neurite outgrowth, while antibodies that bind to uPA but
do not inhibit activity do not alter outgrowth. Time-lapse videomicroscopy
of neurite outgrowth indicates that about 85% of the neurites increase
their rate of outgrowth following exposure to inhibitors of PA. Routinely,
1-2 min after exposure of a growth cone to an inhibitor, there is an
increase in lamellipodial activity at the leading edge of the growth cone
and a decrease in lamellipodial activity on the sides and base of the
growth cone. The increase in the rate of outgrowth combined with the
decrease in lamellipodial activity on the sides of the growth cones results
in neurites being very long and straight in the presence of inhibitors
(persistence time P = 3.7 and 15.3 hr for controls and in the presence of
inhibitors of PA, respectively). PAs released from sympathetic neurons and
PC12 cells interact with 3 different binding sites on the cell surface: (1)
an inhibitor of serine proteases (including uPA and tPA) is bound to the
surface via a heparinase-sensitive site; (2) a uPA- selective binding site
is present in patches on the bottom surface of PC12 cells; and (3) a
tPA-selective binding site with high affinity (KD = 23 +/- 10 nM) and high
capacity (340,000 +/- 130,000 sites/neuron) for 125I-tPA is homogeneously
distributed over the entire surface. Data in the present study are
consistent with PA being involved in neurite outgrowth and open the
possibility of other PA-dependent functions occurring when tPA and/or uPA
interacts with cell surface binding sites.
