A better understanding of immunology of TB can not only lead to the discovery of new immunodiagnostic tools, accelerate and facilitate the assessment of new therapeutic methods, but also find new treatment regimens. In this highlight topic we cover the latest developments in the role of T cells, macrophages, Natural killer(NK) cells, invariant NK T(iN KT) cells and γδ T cells with TB infection. Histologically, TB displays exudative inflammation, proliferative inflammation and productive inflammation depending on the time course. T cells first recognize antigen within the mycobacterially-infected lung, and then activate, differentiate, but the first T cell activation occurs in the draining lymph nodes of the lung. When protective T cells reach sufficient numbers, they can stop bacterial growth. Except for T cells, neutrophils also participate actively in defense against early-phase TB. NK cells are innate lymphocytes which are a first line of defense against mycobacterial infection. Human NK cells use the NKp46, NCRs and NKG2 D receptors to lyse Mycobacterium TB-infected monocytes and alveolar macrophages. NK cells produce not only interferon-γ, but also interleukin(IL)-22, which is induced by IL-15 and DAP-10. iN KT cells show different phenotypes and functions. Many iN KT cells are CD4+,few iN KT cells are CD8+, while an additional fraction of iN KT cells are negative for both CD4 and CD8. γδ T cells represent an early innate defense in antimycobacterial immunity. Studies done in humans and animal models have demonstrated complex patterns of γδ T cell immune responses during chronic TB. Human alveolar macrophages and monocytes can serve as antigen presentation cells for γδ T cells. Furthermore, the predominance of Vγ9Vδ2 T cells in TB has been confirmed.展开更多

The liver keeps a delicate balance between hepatic screening of pathogenic antigens and immune tolerance to self-antigens. Herbal treatments with immunological effects have potential to alter this hepatic immune balance towards either therapeutic side or diseases side by inducing liver injury via hepatotoxicity or initiation of autoimmune diseases. Most commonly known herbal treatments, which have therapeutic effect on liver and IS, have proven via in vitro, in vivo, and/or clinical studies were summarized in this review.展开更多

Great progresses have been achieved in the subject along with the deep development in life science. Modern reproductive immunology includes immunological regulation of fertility, materno-fetal immuno-regu-lation, and neuro-reproductive endocrino-immune network. With the integrated traditional Chinese and western medicine (ICWM) applied to reproductive immunology it has been greatly enriched in research contents and depth. The present review is to introduce the recent progresses in research of integrated medicine on reproductive immunology.展开更多

Nevertheless, this same protective mechanism may also establish a negative consequence in the setting of disorders such as autoimmunity and transplant rejection. In light of the latter, although research has long uncovered main concepts of allogeneic recognition, immune rejection is still the main obstacle to long-term graft survival. Therefore, in order to define effective therapies that prolong graft viability, it is essential that we understand the underlying mediators and mechanisms that participate in transplant rejection. This multifaceted process is characterized by diverse cellular and humoral participants with innate and adaptive functions that can determine the type of rejection or promote graft acceptance. Although a number of mediators of graft recognition have been described in traditional immunology, recent studies indicate that defining rigid roles for certain immune cells and factors may be more complicated than originally conceived. Current research has also targeted specific cells and drugs that regulate immune activation and induce tolerance. This review will give a broad view of the most recent understanding of the allogeneic inflammatory/tolerogenic response and current insights into cellular and drug therapies that modulate immune activation that may prove to be useful in the induction of tolerance in the clinical setting.展开更多

The pace of discovery in the field of immunology has accelerated signifcantly in recent years due to important discover-ies and the implementation of new technologies and methodologies that have become readily accessible to many investigators. WJI is an open-access, peer-reviewed journal, whose preparatory work was initiated on November 30, 2010 and will be offcially published on December 27, 2011. The WJI Editorial Board con-sists of 99 experts in experimental medicine from 23 countries. By taking into account the widespread use of the internet and the necessity that scientifc journals should reach out to wider audiences through the provi-sion of barrier-free information, WJI aims to provide rapid publication through an established system that is targeted at dissemination to the scientific community via online open-access.展开更多

Many such tests are also commonly repeated at intervals, in an effort to facilitate disease monitoring. In general how-ever, immunology test results are often slow to alter. Furthermore, audit activity has indicated that repeated testing accounts for a substantial workload in many immunology services, which may waste resources and compromise the effcient completion of necessary tests. Consequently, the need and appropriate mini-mum interval between repeated testing requires critical evaluation. In this review, the clinical utility of repeat-ed performance of several common immunology inves-tigations has been evaluated, based upon published evidence. In some cases （ e.g. , paraprotein quantifca-tion, or measurement of anti-glomerular basement membrane antibodies）, repeated testing provides vital clinical information and can be justifed on a frequent and individualized basis. However, many other investi-gations provided by immunology services provide less valuable information when used to aid disease moni-toring rather than diagnosis. It is hoped that the data summarized here will facilitate a more evidence-based approach to repeated testing. Such information may also assist with the local implementation of demand management strategies based upon setting of mini-mum retesting intervals for these investigations.展开更多
