The role of myeloid-derived suppressor cells (MDSC) in the inflammaging process.
The role of myeloid-derived suppressor cells (MDSC) in the inflammaging process. Ageing Res Rev. 2018 Sep 21;: Authors: Salminen A, Kaarniranta K, Kauppinen A Abstract A chronic low-grade inflammation is one of the hallmarks of the aging process. This gradually augmenting inflammatory state has been termed inflammaging. Inflammaging is associated with increased myelopoiesis in the bone marrow. This myelopoiesis-biased process increases the generation not only of mature myeloid cells, e.g. monocytes, macrophages, and neutrophils, but also immature myeloid progenitors and myeloid-derived suppressor cells (MDSCs). It is known that the aging process is associated with a significant increase in the presence of MDSCs in the bone marrow, blood, spleen, and peripheral lymph nodes. Consequently, MDSCs will become recruited into inflamed tissues where they suppress acute inflammatory responses and trigger the resolution of inflammation. However, if the perpetrator cannot be eliminated, the long-term presence of MDSCs suppresses the host's immune defence and increases the susceptibility to infections and tumorigenesis. Chronic immunosuppression also impairs the clearance of waste products and dead cells, impairs energy metabolism, and disturbs tissue proteostasis. This immunosuppressive state is reminiscent of the immunosenescence observed in inflammaging. It seems that proinflammatory changes in tissues with aging stimulate the myelopoietic production of MDSCs whi...
This article aims to introduce forensic practitioners to basic concepts in genetics and epigenetics so that they are able to engage with the relevant literature and understand the far-reaching implications for forensic practice. It is becoming increasingly useful for forensic practitioners to appreciate how life experiences are encoded into biology through epigenetics. This paper highlights the potential of genetic and epigenetic research to provide major contributions to real-world practice in the coming years. It provides a modern biopsychosocial perspective on harmful behaviour and helps deepen the understanding of o...

This article discusses ethical considerations and principles and propose use of the 4Es model and core communication skills to address ethical dilemmas in veterinary practice. It reviews literature defining ethical issues in practice and provides case examples to show the application of our proposed methods. The goal is to provide veterinary professionals with an approach they can use to frame and address their own ethical decisions.
One of the most impactful ways to create a dynamic team is to foster diversity and inclusivity within the workplace. Workplaces have become more heterogenous as advances in human, women, and civil rights group have spurred greater labor force participation by members of historically underrepresented groups. Studies have shown that leveraging diversity has important implications for the promotion of positive organization change through facilitation of individual and organization performance. Diverse clientele may be more comfortable and feel more welcome working with people in a diverse workplace.
