Impact of stable ghrelin receptor agonists and antagonists on food intake regulation
Holubová, Martina
The thesis is focused on the effect of ghrelin receptor (GHS-R1a) agonists and antagonist on food intake regulation. Ghrelin is the only known periferally produced orexigenic hormone and the only known acylated hormone. GHS-R1a agonists and antagonists could be useful in the treatment of cachexia and obesity, respectively. In the first part of the thesis, newly designed peptidic GHS-R1a agonists were characterized. The agonists were stabilized by replacing octanoylated Ser3 with a fatty acid coupled to diaminopropionic acid by a stable amide bond. Other noncoded amino acids were also incorporated. Ghrelin analogs were modified by replacing the octanoyl group with another fatty acid, incorporation of the second fatty acid or shortening the peptide chain. Most of the tested GHS-R1a agonists were found to possess high affinities for GHS-R1a (Ki = 10-9 - 10-10 nM) and to activate signaling pathways of ghrelin. After subcutaneous (SC) administration to mice, agonists showed significant and prolonged orexigenic effect. In the second part of the thesis, acute and long-term effects of pseudopeptide GHS- R1a agonist JMV1843 were tested in lean C57BL/6 mice. Acute SC administration of JMV1843 to fed mice increased food intake in a dose-dependent manner (ED50 = 1.94 mg/kg). JMV1843 was stable in blood serum...

Impact of NKR-P1 polymorphism on Ly49 receptors expression in hybrid mouse strains (C57BL/6 x Balb/c, F10-12)
Holubová, Martina ; Fišerová, Anna (advisor) ; Vomastek, Tomáš (referee)
Impact of NKR-P1 polymorphism on Ly49 receptors expression in hybrid mouse strains (C57BL/6 x Balb/c, F10-12) Abstract Natural killer (NK) cells constitute the subpopulation of large granular lymphocytes which mediate spontaneous immune response against infected, transformed or allogeneic cells and thus represent an important component of the innate immunity. NK cells express a wide repertoir of surface receptors which can be either activating or inhibitory and which mediate NK cell recognition and regulation of cytolytic activity. NKR-P1 and Ly49 receptor families belong to the most important murine NK receptors. Both NKR-P1 and Ly49 families are members of C-type lectin-like superfamily of receptors encoded by natural killer gene complex (NKC) on chromosome 6 and include both activating and inhibitory members. The aim of this diploma thesis was to elucidate the impact of Nkr-p1c gene divergence on Ly49 receptors expression and to find out whether the Ly49 and Nkr-p1 gene clusters (which are localized on opposite ends of NKC) are inherited independently or whether the NKC domain is inherited as a complex. The second research interest was to illustrate the influence of the above mentioned divergence on cytotoxic activity of NK cells and tumor growth. In this study, inbred mouse strains C57BL/6 and Balb/c...
