Summary Introduction

Introduction:

Local hormones are a huge group of signaling molecules. These are released from the cells which produce them or are secreted from neighboring cells. Eicosanoid is a primary type of local hormone which is released from fatty acids. It is formed by an enzymatic cascade. It causes the stimulation of cells that produced it (autocrine stimulation) or its neighboring cells (paracrine stimulation). Leukotrienes from damaged tissue cause smooth muscle in local blood vessels to vasodilate or increase the vessel lumen.
