Abstract
Structure and integrity of the mitochondrial network play important roles in many cellular processes. Loss of integrity can lead to the activation of a variety of signalling pathways and affect the cell's response to infections. The activation of such mitochondria-mediated cellular responses has implications for infection recognition, signal transduction and pathogen control. Although we have a basic understanding of mitochondrial factors such as mitochondrial DNA or RNA that may be involved in processes like pro-inflammatory signalling, the diverse roles of mitochondria in host defence remain unclear. Here we will first summarise the functions of mitochondria in the host cell and provide an overview of the major known mitochondrial stress responses. We will then present recent studies that have contributed to the understanding of the role of mitochondria in infectious diseases and highlight a number of recently investigated models of bacterial and viral infections.
期刊介绍：
Medical Microbiology and Immunology (MMIM) publishes key findings on all aspects of the interrelationship between infectious agents and the immune system of their hosts. The journal´s main focus is original research work on intrinsic, innate or adaptive immune responses to viral, bacterial, fungal and parasitic (protozoan and helminthic) infections and on the virulence of the respective infectious pathogens.
MMIM covers basic, translational as well as clinical research in infectious diseases and infectious disease immunology. Basic research using cell cultures, organoid, and animal models are welcome, provided that the models have a clinical correlate and address a relevant medical question.
The journal also considers manuscripts on the epidemiology of infectious diseases, including the emergence and epidemic spreading of pathogens and the development of resistance to anti-infective therapies, and on novel vaccines and other innovative measurements of prevention.
The following categories of manuscripts will not be considered for publication in MMIM:
submissions of preliminary work, of merely descriptive data sets without investigation of mechanisms or of limited global interest,
manuscripts on existing or novel anti-infective compounds, which focus on pharmaceutical or pharmacological aspects of the drugs,
manuscripts on existing or modified vaccines, unless they report on experimental or clinical efficacy studies or provide new immunological information on their mode of action,
manuscripts on the diagnostics of infectious diseases, unless they offer a novel concept to solve a pending diagnostic problem,
case reports or case series, unless they are embedded in a study that focuses on the anti-infectious immune response and/or on the virulence of a pathogen.
