Involvement of chemosensory proteins in host plant searching in the bird cherry-oat aphid.

Insect Sci 2020 Aug 12. Epub 2020 Aug 12.

State Key Laboratory of Crop Stress Biology for Arid Areas, Key Laboratory of Crop Pest Integrated Pest Management on the Loess Plateau of Ministry of Agriculture and Rural Affairs, Northwest A&F University, Yangling, Shaanxi Province, 712100, China.

Chemosensory systems are considered to play an important role in host plant selection in herbivorous insects. However, few studies have focused on chemosensory proteins (CSPs) for aphid host-location mechanisms. The roles of CSPs in searching for different Poaceae species (wheat, barley, triticale, maize and sorghum) were tested in Rhopalosiphum padi, an important cereal pest. Read More

Elevated Prevalence of Azole-Resistant Aspergillus fumigatus in Urban versus Rural Environments in the United Kingdom.

Antimicrob Agents Chemother 2019 09 23;63(9). Epub 2019 Aug 23.

MRC Centre for Global Infectious Disease Analysis, Department of Infectious Disease Epidemiology, Imperial College London, London, United Kingdom.

Azole resistance in the opportunistic pathogen is increasing, dominated primarily by the following two environmentally associated resistance alleles: TR/L98H and TR/Y121F/T289A. By sampling soils across the South of England, we assess the prevalence of azole-resistant (AR) in samples collected in both urban and rural locations. We characterize the susceptibility profiles of the resistant isolates to three medical azoles, identify the underlying genetic basis of resistance, and investigate their genetic relationships.

ISOLATION, CHARACTERIZATION AND IMMUNOCHEMICAL STUDIES ON FIBROUS PROTEINS FROM COWRY SHELL , LINNAEUS).

Afr J Tradit Complement Altern Med 2017 23;14(1):110-122. Epub 2016 Nov 23.

Department of Biochemistry, ObafemiAwolowo University, Ile-Ife, Nigeria.

Background: Biomaterials are non-drug substances used to treat, enhance or replace functions of body tissues or organs. Natural sources of biomaterials have recently become the focus of several research activities. Cowry shell constitutes one of the most promising natural sources of biomaterials because of its chemical stability, biodegradability and biocompatibility in the body. Read More

Therapeutic efficacy of a polysaccharide isolated from Cordyceps sinensis on hypertensive rats.

Int J Biol Macromol 2016 Jan 30;82:308-14. Epub 2015 Sep 30.

Department of Ultrasonography, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, No. 1095 Jiefang Street, Wuhan, China.

This study was aimed to investigate the antihypertensive effect of a polysaccharide fraction from Cordyceps sinensis on spontaneously hypertensive rats (SHR). The CSP1, one component of Cordyceps sinensis polysaccharides (CSP), was obtained after water extraction, deproteinization, de-colorization and purification with DEAE-cellulose 52. And a more homogeneous component CSP1-2 was obtained using Sepharose CL-6B chromatography. Read More

Pherotypes of co-colonizing pneumococci among Portuguese children.

Microb Drug Resist 2012 Dec 12;18(6):550-4. Epub 2012 Jul 12.

Laboratory of Molecular Microbiology of Human Pathogens, Instituto de Tecnologia Química e Biológica, Universidade Nova de Lisboa, Oeiras, Portugal.

A recent study showed that pneumococcal pherotypes often coexist in the nasopharynx and suggested that the impact of pherotype-mediated fratricide on competition is limited. We determined the impact of pherotype (or competence-stimulating peptide [CSP]) on pneumococcal nasopharyngeal co-colonization. Of 184 nasopharyngeal samples yielding two serotypes, 39. Read More

The variable C-terminus of cysteine string proteins modulates exocytosis and protein-protein interactions.

Biochemistry 2004 Dec;43(51):16212-23

Institut Européen de Chimie et Biologie, Pôle Biologie Cellulaire et Moléculaire, JE 2390, 33607 Pessac/Bordeaux, France.

Cysteine string proteins (Csps) are vesicle proteins involved in neurotransmission and hormone exocytosis. They are composed of distinct domains: a variable N-terminus, a J-domain followed by a linker region, a cysteine-rich string, and a C-terminus which diverges among isoforms. Their precise function and interactions are not fully understood. Read More

Interaction of cysteine string proteins with the alpha1A subunit of the P/Q-type calcium channel.

J Biol Chem 1998 May;273(22):13488-92

Institut National de la Santé et de la Recherche Médicale, Unité 464, Institut Jean Roche, Faculté de Médecine Secteur Nord, Bd. Pierre Dramard, 13916 Marseille Cedex 20, France.

Cysteine string proteins (Csps) are J-domain chaperone proteins anchored at the surface of synaptic vesicles. Csps are involved in neurotransmitter release and may modulate presynaptic calcium channel activity, although the molecular mechanisms are unknown. Interactions between Csps, proteins of the synaptic core (SNARE) complex, and P/Q-type calcium channels were therefore explored. Read More
