Special Issue Information

Dear Colleagues,

Macrophages are critical mediators of tissue homeostasis. They are generally considered to be one of the first lines of defense against pathogens, as they employ a range of strategies to phagocytose and kill pathogens and play important roles in orchestrating the protective inflammatory response through pattern recognition receptors. In addition, macrophages play an important role in removing cellular debris and repairing tissues. They are strategically positioned throughout the body’s tissues, either established prenatally (embryonic origin) and maintained through adulthood or derived from tissue-infiltrating monocytes (hematopoietic origin).

For this Special Issue entitled "Macrophages during Inflammation", we welcome the submission of original research and review articles covering a broad range of topics, including: macrophage-pathogen interactions in infectious diseases: detection, phagocytosis, and inflammatory responses; molecular mechanisms for inflammatory signaling in macrophages; plasticity of macrophage function; tolerance and trained immunity in macrophages; immunomodulation of macrophage function; and influence of origin on macrophage functional phenotype. Furthermore, macrophages are important to the development of several human diseases. Therefore, this Special Issue may also include topics related to pulmonary, cardiovascular, or metabolic inflammatory diseases, neurodegeneration, aging, or cancer.

We look forward to your contribution.

As highlighted by the COVID-19 global pandemic, elderly individuals comprise the majority of cases of severe viral infection outcomes and death. A combined inability to control viral replication and exacerbated inflammatory immune activation in elderly patients causes irreparable immune-mediated tissue pathology in response to infection. Key to these responses are type I, II, and III interferons (IFNs), which are involved in inducing an antiviral response, as well as controlling and suppressing inflammation and immunopathology. IFNs support monocyte/macrophage-stimulated immune responses that clear infection and promote their immunosuppressive functions that prevent excess inflammation and immune-mediated pathology. The timing and magnitude of IFN responses to infection are critical towards their immunoregulatory functions and ability to prevent immunopathology. Aging is associated with multiple defects in the ability of macrophages and dendritic cells to produce IFNs in response to viral infection, leading to a dysregulation of inflammatory immune responses. Understanding the implications of aging on IFN-regulated inflammation will give critical insights on how to treat and prevent severe infection in vulnerable individuals. In this review, we describe the causes of impaired IFN production in aging, and the evidence to suggest that these impairments impact the regulation of the innate and adaptive immune response to infection, thereby causing disease pathology.
