ReviewCross-Domain and Viral Interactions in the MicrobiomeThe importance of the microbiome to human health is increasingly recognized and has become a major focus of recent research. However, much of the work has focused on a few aspects, particularly the bacterial component of the microbiome, most frequently in the gastrointestinal tract.
- ReviewExperimental Design, Population Dynamics, and Diversity in Microbial Experimental Evolution...
In experimental evolution, laboratory-controlled conditions select for the adaptation of species, which can be monitored in real time. Despite the current popularity of such experiments, nature's most pervasive biological force was long believed to be observable only on time scales that transcend a researcher's life-span, and studying evolution by natural selection was therefore carried out solely by comparative means.
ReviewCRISPR Tools To Control Gene Expression in BacteriaCRISPR-Cas systems have been engineered as powerful tools to control gene expression in bacteria. The most common strategy relies on the use of Cas effectors modified to bind target DNA without introducing DNA breaks. These effectors can either block the RNA polymerase or recruit it through activation domains. Here, we discuss the mechanistic details of how Cas effectors can modulate gene expression by blocking transcription initiation...
ReviewCytosolic Recognition of Microbes and Pathogens: Inflammasomes in ActionInfection is a dynamic biological process underpinned by a complex interplay between the pathogen and the host. Microbes from all domains of life, including bacteria, viruses, fungi, and protozoan parasites, have the capacity to cause infection.
ReviewPoly(ADP-Ribose) Polymerases in Host-Pathogen Interactions, Inflammation, and ImmunityThe literature review presented here details recent research involving members of the poly(ADP-ribose) polymerase (PARP) family of proteins. Among the 17 recognized members of the family, the human enzyme PARP1 is the most extensively studied, resulting in a number of known biological and metabolic roles.
ReviewGlobal Organization and Proposed Megataxonomy of the Virus WorldViruses and mobile genetic elements are molecular parasites or symbionts that coevolve with nearly all forms of cellular life. The route of virus replication and protein expression is determined by the viral genome type. Comparison of these routes led to the classification of viruses into seven “Baltimore classes” (BCs) that define the major features of virus reproduction. However, recent phylogenomic studies identified multiple...
ReviewCurli-Containing Enteric Biofilms Inside and Out: Matrix Composition, Immune Recognition, and Disease ImplicationsBiofilms of enteric bacteria are highly complex, with multiple components that interact to fortify the biofilm matrix. Within biofilms of enteric bacteria such as Escherichia coli and Salmonella species, the main component of the biofilm is amyloid curli. Other constituents include cellulose,...
ReviewInterplay between Peptidoglycan Biology and Virulence in Gram-Negative PathogensThe clinical and epidemiological threat of the growing antimicrobial resistance in Gram-negative pathogens, particularly for β-lactams, the most frequently used and relevant antibiotics, urges research to find new therapeutic weapons to combat the infections caused by these microorganisms. An essential previous step in the development of these therapeutic solutions is to identify their potential targets in the biology of the pathogen....
ReviewThe Use of Defined Microbial Communities To Model Host-Microbe Interactions in the Human GutThe human intestinal ecosystem is characterized by a complex interplay between different microorganisms and the host. The high variation within the human population further complicates the quest toward an adequate understanding of this complex system that is so relevant to human health and well-being.
