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.
ReviewGut Microbiota and Colonization Resistance against Bacterial Enteric InfectionThe gut microbiome is critical in providing resistance against colonization by exogenous microorganisms. The mechanisms via which the gut microbiota provide colonization resistance (CR) have not been fully elucidated, but they include secretion of antimicrobial products, nutrient competition, support of gut barrier integrity, and bacteriophage deployment.
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....
ReviewDoes Gender Bias Still Affect Women in Science?The percentage of women employed in professional scientific positions has been low but is increasing over time. The U.S. National Institutes of Health and the National Science Foundation have both implemented programs to improve women’s participation in science, and many universities and companies have diversity and equity programs.
ReviewRegulation of Bacterial Gene Expression by Transcription AttenuationA wide variety of mechanisms that control gene expression in bacteria are based on conditional transcription termination. Generally, in these mechanisms, a transcription terminator is located between a promoter and a downstream gene(s), and the efficiency of the terminator is controlled by a regulatory effector that can be a metabolite, protein, or RNA.
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.
ReviewOxidoreductases and Reactive Oxygen Species in Conversion of Lignocellulosic BiomassBiomass constitutes an appealing alternative to fossil resources for the production of materials and energy. The abundance and attractiveness of vegetal biomass come along with challenges pertaining to the intricacy of its structure, evolved during billions of years to face and resist abiotic and biotic attacks.
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.
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,...
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.
