CRISPR : methods and protocols by Magnus Lundgren( Book )

1 edition published in 2015 in English and held by 49 WorldCat member libraries worldwide

This volume presents a list of cutting-edge protocols for the study of CRISPR-Cas defense systems and their applications at the genomic, genetic, biochemical and structural levels. CRISPR: Methods and Protocols guides readers through techniques that have been developed specifically for the analysis of CRISPR-Cas and techniques adapted from standard protocols of DNA, RNA and protein biology. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, CRISPR: Methods and Protocols provides a broad list of tools and techniques to study the interdisciplinary aspects of the prokaryotic CRISPR-Cas defense systems
Functional analysis of the group A streptococcal luxS/AI-2 system in metabolism, adaptation to stress and interaction with host cells by Maria Siller( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

Background The luxS /AI-2 signaling pathway has been reported to interfere with important physiological and pathogenic functions in a variety of bacteria. In the present study, we investigated the functional role of the streptococcal luxS /AI-2 system in metabolism and diverse aspects of pathogenicity including the adaptation of the organism to stress conditions using two serotypes of Streptococcus pyogenes , M1 and M19. Results Exposing wild-type and isogenic luxS -deficient strains to sulfur-limited media suggested a limited role for luxS in streptococcal activated methyl cycle metabolism. Interestingly, loss of luxS led to an increased acid tolerance in both serotypes. Accordingly, luxS expression and AI-2 production were reduced at lower pH, thus linking the luxS /AI-2 system to stress adaptation in S. pyogenes . luxS expression and AI-2 production also decreased when cells were grown in RPMI medium supplemented with 10% serum, considered to be a host environment-mimicking medium. Furthermore, interaction analysis with epithelial cells and macrophages showed a clear advantage of the luxS -deficient mutants to be internalized and survive intracellularly in the host cells compared to the wild-type parents. In addition, our data revealed that luxS influences the expression of two virulence-associated factors, the fasX regulatory RNA and the virulence gene sibA ( psp ). Conclusion Here, we suggest that the group A streptococcal luxS /AI-2 system is not only involved in the regulation of virulence factor expression but in addition low level of luxS expression seems to provide an advantage for bacterial survival in conditions that can be encountered during infections
Etude fonctionnelle de la MMp - 12 de macrophage en vue de son ciblage thérapeutique dans la broncho-pneumopathie chronique obstructive by Anne-Sophie Lamort( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

Chronic obstructive pulmonary disease or COPD is a lung disease caused by tobacco smoking. This is a chronic and non reversible disease for which no curative treatment is available yet. Permanent inflammation of the airways is a hallmark of COPD because immune cells such as neutrophils and macrophages are continuously recruited. Once activated, these cells release numerous active proteases which participate to the degradation of structural proteins of the lungs such as elastin, leading to lung emphysema as a consequence of lung alveoli degradation. Among the different proteases found in the lungs, macrophage MMP-12 has been reported to play a key pathogenic role in COPD development
