Abstract

Interferons (IFN) belong to the family of cytokines and have been described first in the late 1950s as an inhibitory factor of viral replication. Since then, the impact of interferon has been greatly expanded and its function comprises a role not only in different types of infection, cancer and autoimmunity but importantly also in immunehomeostasis. IFN have important anti-viral effects but it is becoming more and more evident that they are true immunomodulators and have an important impact on the development and maintenance of innate and adaptive immunity.

Abstract

Successful containment of an infection is dependent on both innate and adaptive immune response. Cytokines are essential effectors of both of these systems. In particular, type I interferons (IFN-I) are important components of early innate immunity against an infection. However, the production of IFN-I could serve as a double edge sword, either containing an infection or enhancing susceptibility. For example, IFN-I, which is essential for early containment of viral infections, has been shown to be detrimental to the host during bacterial infections. In fact, recent significant reports have shown that influenza virus induced IFN-I responses can enhance the host susceptibility to secondary bacterial infections. These recent reports highlight the expanding immunoregulatory role of IFN-I in the host immunity. With these recent findings in mind, the aim of this research topic is to welcome novel data, opinion and literature reviews on the newly identified dual functions of IFN-I. This research topic wills focus on the following areas of IFN-I: 1) a detrimental role of IFN-I during primary bacterial infection; 2) a detrimental role of viral infection induced IFN-I during secondary bacterial infections; 3) evolutionary pressure that drove detrimental IFN-I response during primary bacterial infection; and 4) does benefit of IFN-I responses during primary viral infections outweigh the adverse consequences of IFN-I mediated enhanced susceptibility to secondary bacterial infections.

Abstract

Autoinflammation, as a relatively new field in clinical rheumatology, has gained an increasing importance in recent years. The number of identified entities and affected patients has gradually increased, and some of the involved pathways have already been identified. This progress allows a deeper understanding of closely linked diseases, namely, inflammasomopathies, interferonopathies, Relo-pathies, and proteasome associated syndromes. These insights have not only improved their classification but also helped to identify new treatment targets of pro-inflammatory cytokines, including IL-1ß, IL-6, interferon-, and TNF-alpha. Nevertheless, there is still a high medical need, especially in reliable outcome measures, for confirmation of data from controlled clinical trials and, finally, also for long-term experience from registers. This issue welcomes all types of papers on the broad spectrum of clinical characteristics, prognosis, pathophysiology, and treatment of autoinflammatory diseases. The goal of this Special Issue is to further raise awareness of autoinflammatory processes and to better separate them from well-established autoimmune diseases. It is clear that we have entered a new age in this complex field, linking rheumatology even closer to immunology.

Abstract

The regenerative and immunomodulatory properties of mesenchymal stem cells (MSCs) have made these cells the focus of multiple pre-clinical studies and clinical trials. While the results from these clinical studies have established that MSCs are safe, the efficacy of these cells is not as well-established. In this regard, there have been increased efforts towards generating potentiated/activated MSCs with enhanced therapeutic efficacy. Research on the mechanisms for enhancing MSC potency and efficacy is an area of active study with great potential for translation into clinical settings. The purpose of this book is to bring together recent research from a broad range of topics relating to potentiation strategies for enhancing MSC therapeutic efficacy, including growth factor pre-conditioning, hypoxia, and 3D culture. The research compiled in this book increases the basic understanding of MSC culture techniques and describes some MSC preparations for potential novel therapeutic applications.

Abstract

Zika virus (ZIKV), one of the flavivirus family members transmitted by mosquitos, was declared a Public Health Emergency of International Concern by the WHO in February 2016 because of clusters of newborn microcephaly cases and other neurological disorders in Brazil. Most ZIKV infections result in a self-limited flu-like febrile disease, however, if contracted during pregnancy, the virus can also infect fetuses and cause a spectrum of birth defects known as congenital Zika syndrome. To date, no vaccines or antiviral drugs are licensed for ZIKV, and the virus has spread and become endemic to many tropical and sub-tropical countries. Included in this book are thirteen reports addressing diverse aspects of ZIKV–host interactions. These studies range from basic science to clinical research. It is expected that findings from these studies will contribute to a better understanding of the host cells interacting with ZIKV, and may serve as the basis for new diagnostics, antiviral therapies, and vaccine design.

Abstract

Rheumatoid Arthritis (RA) is a chronic inflammatory disease leading to joint inflammation and destruction. Treatment of RA includes the use of conventional (cs), biologic (b) disease-modifying anti-rheumatic drugs (DMARDs), and oral or intraarticular (IA) glucocorticoids (GCs). All different classes of drugs have shown to halt disease progression in clinical studies. In real life, a physician has more options than just adding or switching to a new ts/bDMARD if any kind of DMARDs has failed. They can modify or optimize the therapy with concomitant csDMARDs, and oral or IA-GC can be added to the treatment regimen. The EULAR states that therapeutic adjustment including the "optimization of csDMARDs dose or route of administration or intra-articular injections of GCs" is recommended. Thus, a new therapeutic agent can be embedded in a whole strategy with parallel optimization of the csDMARD and GC treatment. The idea of treating to target (T2T) for the treatment of RA patients has been around since the late 1990s. Many clinical studies (Ticora, BsSt, Camera) have demonstrated the superiority of a T2T approach. When I talk to physicians, I understand that most of them only rarely inject joints with GC. Therefore, I would like to create an issue on the T2T approach in reality including primary data, reviews, and real-life data demonstrating the general opinion and execution of T2T in treating RA.

Abstract

In this Special Issue, we present the state of the art in the field of pig genetics and genomics, including the identification of gene candidates linked to important pig traits and to nutritional modifications, with the aim of collecting the most recent advances. The published manuscripts focused on high-throughput methodologies, such as RNA sequencing, ATAC-seq, MACE-seq, chip-seq, and RRBS, and covered other fields of pig genetics. The pig (Sus scrofa) is the most common large mammal in the world. The Sus genus includes domestic pig and wild boar. Since the draft reference genome sequence of S. scrofa was assembled in 2012, the processes of identification of genes related to important phenotypic traits and of search of genetic markers for pig selection have been significantly refined. In addition, the newest wide-range high-throughput techniques, including microarrays, next-generation sequencing, and the recent PacBio sequencing platform providing ultra-long sequencing reads, allow identifying gene mutations and gene candidates throughout the whole genome, transcriptome, or epigenome and estimating quantitative traits important for breeding as well as the genetic backgrounds of inherited diseases.

Abstract

Zika virus (ZIKV) is a mosquito-borne member of the Flaviviridae family that historically has been associated with mild febrile illness. However, the recent outbreaks in Brazil in 2015 and its rapid spread throughout South and Central America and the Caribbean, together with its association with severe neurological disorders—including fetal microcephaly and Guillain-Barré syndrome in adults—have changed the historic perspective of ZIKV. Currently, ZIKV is considered an important public health concern that has the potential to affect millions of people worldwide. The significance of ZIKV in human health and the lack of approved vaccines and/or antiviral drugs to combat ZIKV infection have triggered a global effort to develop effective countermeasures to prevent and/or treat ZIKV infection. In this Special Issue of Viruses, we have assembled a collection of 32 research and review articles that cover the more recent advances on ZIKV molecular biology, replication and transmission, virus–host interactions, pathogenesis, epidemiology, vaccine development, antivirals, and viral diagnosis.
