Immunology review

Naoshi Nishida, Masatoshi Kudo
Despite recent advances in the treatment of hepatocellular carcinoma (HCC), the prognosis of patients with advanced stage of disease remains unfavorable. Several immune therapies have been applied to HCC, and their responses have not been satisfactory. The immune response to cancer is determined by the balance between the antigenicity of the tumor and the microenvironment of cancer tissues. Generally, accumulated genetic mutations are observed in HCC, which may lead to increased neoantigens on cancer cells with high antigenicity...

American cutaneous leishmaniasis (ACL) is a major public health problem caused by vector-borne protozoan intracellular parasites from the genus Leishmania, subgenera Viannia and Leishmania. Asymptomatic infection is the most common outcome after Leishmania inoculation. There is incomplete knowledge of the biological processes explaining the absence of signs or symptoms in most cases while other cases present a variety of clinical findings. Most studies of asymptomatic infection have been conducted in areas of endemic visceral leishmaniasis...

A prerequisite for tumor evolution toward a malignant state is the establishment of cell intrinsic and extrinsic mechanisms of immune suppression (Hanahan and Weinberg, 2000, 2011; Schreiber, Old, and Smyth, 2011). Widespread recruitment of Foxp3(+) regulatory T cells (TREG) is a prevailing means to dampen antitumor immunity. Advances in the characterization of TREG cell heterogeneity and physiological function of tissue resident TREG cells unfold new possibilities for nontraditional tumor-promoting functions of intratumoral TREG cells...

The effectiveness of conventional cancer chemotherapy is hampered by the occurrence of multidrug resistance (MDR) in tumor cells. Although many studies have reported the development of novel MDR chemotherapeutic agents, clinical success is lacking owing to the high associated toxicity. Nanoparticle-based delivery of chemotherapeutic drugs has emerged as alternative approach to treat MDR cancers via exploitation of leaky vasculature in the tumor microenvironment. Accordingly, functionalization of nanoparticles with target specific ligands can be employed to achieve significant improvements in the treatment of MDR cancer...

In the last twenty years, our comprehension of the molecular mechanisms involved in formation, progression and complication of atherosclerotic plaque has advanced significantly and the main role of inflammation and immunity in this phenomenon is now largely accepted. Accumulating evidence highlight the crucial role of different inflammatory and immune cells, such as monocytes and T-lymphocytes, in the pathophysiology of atherosclerotic lesion, particularly in contributing to its complications, such as rupture or ulceration...

Malignant glioma is the most common and a highly aggressive cancer in the central nervous system (CNS). Cancer immunotherapy, strategies to boost the body's anti-cancer immune responses instead of directly targeting tumor cells, recently achieved great success in treating several human solid tumors. Although once considered "immune privileged" and devoid of normal immunological functions, CNS is now considered a promising target for cancer immunotherapy, featuring the recent progresses in neurobiology and neuroimmunology and a highly immunosuppressive state in malignant glioma...

PURPOSE OF REVIEW: Norovirus infection is an emerging chronic infection in immunocompromised hosts. The aim of this review is to discuss the pathophysiology of Norovirus infection and explore mechanistic models for chronic infection/shedder state, especially in patients with immune deficiency diseases. RECENT FINDINGS: Chronic Norovirus infection is increasingly associated with enteropathy associated with both primary and secondary immune deficiency diseases. There is an ongoing debate in the immune deficiency community whether it is truly a causative agent for the enteropathy or it is an innocent bystander...

Nonalcoholic fatty liver disease (NAFLD) is a globally observed metabolic disease with high prevalence both in adults and children. However, there is no efficient medication available yet. Increased evidence indicates that berberine (BBR), a natural plant product, has beneficial effects on NAFLD, though the mechanisms are not completely known. In this review, we briefly summarize the pathogenesis of NAFLD and factors that influence the progression of NAFLD, and focus on the potential mechanisms of BBR in the treatment of NAFLD...

Secondhand smoke exposure (SHSe) has multiple adverse effects on lung function and growth, nutrition, and immune function in children; it is increasingly being recognized as an important modifier of disease severity for children with chronic diseases such as cystic fibrosis (CF). This review examines what is known regarding the prevalence of SHSe in CF, with the majority of reviewed studies utilizing parental-reporting of SHSe without an objective biomarker of exposure. A wide range of SHSe is reported in children with CF, but under-reporting is common in studies involving both reported and measured SHSe...

Connective tissue diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis, and scleroderma, have a strong predilection for women and are associated with a marked increase in the prevalence of hypertension. The mechanisms leading to the increased risk of hypertension in these patients remain unclear; however, they are likely related to immune mediated changes in cardiovascular and renal function. Over the past several years, we have elucidated a number of factors that contribute to the development of hypertension during SLE using a widely established experimental model of SLE, the female NZBWF1 mouse...

PURPOSE OF REVIEW: Primary immunodeficiencies (PIDs) are inherited conditions where components of the immune system are missing or dysfunctional. Over 300 genes have been causally linked to monogenic forms of PID, including a number that regulate the actin cytoskeleton. The majority of cytoskeletal defects disrupt assembly and disassembly of filamentous actin in multiple immune cell lineages impacting functions such as cell migration and adhesion, pathogen uptake, intercellular communication, intracellular signalling, and cell division...

Dendritic cells (DCs) are professional antigen presenting cells that consist of functionally and phenotypically heterogeneous populations. Monocyte derived dendritic cells (moDCs) are a DC subset that have been attracting increasing interest due to their potent influence on adaptive immune function and their rapid accumulation upon an inflammatory stimulus. Whilst early studies on moDCs mainly addressed infection, their emergence and function in other settings such as autoimmunity and allogeneic organ transplantation are now being increasingly appreciated...
