Как отправить get к redis при получении сообщения в канале?

import txredisapi as redis

class RedisListenerProtocol(redis.SubscriberProtocol):
    def connectionMade(self):
        self.subscribe("channelName")
    def messageReceived(self, pattern, channel, message):
        print "pattern=%s, channel=%s message=%s" %(pattern, channel, message)
        if channel == "a": 
            XXXXX?
    def connectionLost(self, reason):
        print "lost connection:", reason

class RedisListenerFactory(redis.SubscriberFactory):
    maxDelay = 120
    continueTrying = True
    protocol = RedisListenerProtocol
