Calcium phosphate (CaP) based materials are widely recognized as the most suitable matrix for bone tissue engineering. The cationic and anionic substitution of CaP structure by the elements and groups of biological importance is the effective way to

Miniature Ca2+ channels in excised plasma-membrane patches: activation by IP3

Autor: Svetlana B. Semyonova, A G Mamin, Galina N. Mozhayeva, K I Kiselyov

Publikováno v: Pflugers Archiv : European journal of physiology. 437(2)

In the present work, we characterized the receptor properties and the conductive features of the inositol (1,4,5)-trisphosphate (IP3)-activated Ca2+ channels present in excised plasma-membrane patches obtained from mouse macrophages and A431 cells. W

The Tl2+ paramagnetic defects dynamics in K2SeO4 crystals

Autor: V. Efimov, G. Mamin

Scopus-Elsevier

The anomalous temperature dependences of EPR spectrum of Tl2+ ions in K2SeO4 crystals were studied. These anomalies are produced by the Tl2+ noncentral motion. The character of interaction between noncentral defects and the incommensurate wave was de

Low-conductance high selective inositol (1,4,5)-trisphosphate activated Ca2+ channels in plasma membrane of A431 carcinoma cells

Autor: Svetlana B. Semyonova, Galina N. Mozhayeva, A G Mamin, K I Kiselyov

Publikováno v: FEBS letters. 407(3)

In many cells, activation of receptors coupled to PIP2 turnover results in Ca2+ release from the intracellular stores accompanied by Ca2+ influx across the PM. It is not well established yet whether Ca2+ influx is activated by IP3 or by an unknown si

[A new type of IP3-sensitive highly selective calcium channels of low conductance in the plasma membrane of carcinoma A 431 cells]

Autor: K I, Kiselev, A G, Mamin, S B, Semenova, G N, Mozhaeva

Publikováno v: Tsitologiia. 39(6)

Application of 0.2-15.0 mM inositol 1,4,5-trisphosphate (IP3) to excised plasma membrane patches from A 431 cells induced activity of low conductance channels that were highly selective for Ca2+ and Ba2+. With 100 mM Ca2+ or 105 mM Ba2+, the channel

Effect of intracellular calcium on ATP-activated, GTP-dependent calcium channels in rat macrophages

Autor: Galina N. Mozhayeva, A G Mamin, K I Kiselyov

Publikováno v: The Journal of physiology. 491

1. In order to study the effect of intracellular free Ca2+ concentration ([Ca2+]i) on the activity of ATP-activated, GTP-dependent Ca2+ channels in rat macrophages, experiments were performed using the inside-out configuration of the patch-clamp tech

ATP-activated inward current and calcium-permeable channels in rat macrophage plasma membranes

Autor: Elena Kaznacheyeva, A. P. Naumov, Y A Kuryshev, Galina N. Mozhayeva, A G Mamin, K I Kiselyov

1. To study mechanisms of receptor-operated Ca2+ influx in non-excitable cells, membrane currents of rat peritoneal macrophages were recorded using whole-cell cell-attached and outside-out configurations of the patch clamp technique. Under whole-cell

ATP-operated calcium-permeable channels activated via a guanine nucleotide-dependent mechanism in rat macrophages

Autor: A G Mamin, Y A Kuryshev, K I Kiselyov, Galina N. Mozhayeva, A. P. Naumov, Elena Kaznacheyeva

Publikováno v: The Journal of physiology. 486

1. To elucidate the possible involvement of a G protein in ATP-evoked Ca(2+)-permeable channel activity, membrane currents of rat peritoneal macrophages were recorded using inside-out and cell-attached configurations of the patch clamp technique. 2.
