Conference: "Signaling Systems, Venoms and Adhesives: Recurring Themes and Variations" held on October 13-16, 1991at Baltimore, MD.

建议为1991年10月13日至16日举行的第二届国际海洋生物技术会议（IMBC' 91）举行为期半天的题为“信号系统、毒液和粘合剂：反复出现的主题和变化”的专题讨论会。本次研讨会汇集了研究海洋生物的科学家，他们的研究对我们的理解做出了重大贡献：(1)外源性化学兴奋剂、神经递质和激素的受体系统，(2)抑制特定受体的物质，以及(3)防水粘合剂的生物合成。这些看似不同的主题被反复出现的主题整合在一起，这些主题在受体结构、转导机制以及具有不同功能的类似分子的合成和使用中都很明显。会议将讨论以下议题：受体介导的幼虫定居，一种特定受体在棘皮动物精子和哺乳动物细胞上的复发，阻断特定受体和离子通道的毒液家族的进化，多肽、类固醇和前列腺素作为内源性激素和外源性信息素的作用，儿茶酚部分结合到神经递质和粘接剂中。会议内容将由主办单位整理整理后在《生物学通报》上发表

A one-half day Symposium, entitled "Signaling Systems, Venoms and Adhesives: Recurring Themes and Variations", is proposed for the Second International Marine Biotechnology Conference (IMBC' 91), October 13-16, 1991. The proposed Symposium assembles scientists whose studies with marine organisms make major contributions to our understanding of: (1) receptor systems for exogenous chemostimulants, neurotransmitters and hormones, (2) substances inhibiting specific receptors, and (3) the biosynthesis of waterproof adhesives. These seemingaly disparate subjects are integrated by recurring themes apparent in receptor structure, mechanisms of transduction, and the synthesis and employment of similar molecules for diverse functions. The following topics will be discussed: receptor-mediated larval settlement, the recurrence of a defined receptor type on echinoderm spermatozoa and mammalian cells, the evolution of families of venoms blocking specific receptors and ion channels, the role of peptides, steroids and prostaglandins as both endogenous hormones and exogenous pheromones and the incorporation of the catechol moiety into both neurotransmitters and adhesives. The Symposium contents will be summarized and integrated by the organizers for publication in the Biological Bulletin.//
