The structure and properties of different members of a large family of small heat shock proteins (sHsp) playing an important role in cell homeostasis are described. Participation of the N-terminal domain in formation of large oligomers and chaperone activity of sHsp is analyzed. The structure of the α-crystallin domain of sHsp is characterized and the role(More)
From 1994 to 2011, over 7000 individuals of small mammals were captured and examined for ticks in the natural foci of ixodid tick-borne borrelioses (ITBB) in the Middle Urals (Chusovskoy District of Perm Territory). Alongside with the taiga tick (Ixodes persulcatus), which is the main Borrelia vector, approximately 5700 feeding individuals of Ixodes(More)
The nested PCR method with primers flanking a conserved fragment of the Babesia microti ss-rDNA gene was used to examine 834 larvae of Ixodes trianguliceps ticks engorged to a varying degree, taken off 237 hosts of 12 species (rodents and insectivores). The hosts were collected in southern taiga forests in the lowmountain area of the Middle Urals (Chusovoi(More)
Classification of small heat shock proteins (sHsp) is presented and processes regulated by sHsp are described. Symptoms of hereditary distal neuropathy are described and the genes whose mutations are associated with development of this congenital disease are listed. The literature data and our own results concerning physicochemical properties of HspB1(More)
The interaction of human small heat shock protein HspB1, its point mutants associated with distal hereditary motor neuropathy, and three other small heat shock proteins (HspB5, HspB6, HspB8) with the light component of neurofilaments (NFL) was analyzed by differential centrifugation, analytical ultracentrifugation, and fluorescent spectroscopy. The(More)
Based on analysis of original and literature data, it is concluded that effective transmission of B. microti by the tick I. persulcatus is prevented by the following main permanent eco-parasitological factors: lack of pronounced anthropophily in the tick nymphs; low rates of spontaneous invasion of unfed adults; a short duration of the parasitic phase on(More)
