Fig. 3From: The contribution of lysophosphatidic acid receptors in the response of human lower esophageal sphincter under the electrical field stimulationEffect of the selective LPA1 and LPA3 receptor antagonist (Ki16425) on the EFS relaxation of the clasp fiber. The selective LPA1 and LPA3 receptor antagonist produced no significant change in the responses (P > 0.05). LPA: Lysophosphatidic acid; EFS: Electrical field stimulationBack to article page
