Human cytomegalovirus (HCMV) encodes numerous proteins and microRNAs that function to evade the immune response and allow the virus to replicate and disseminate in the face of a competent innate and acquired immune system. The establishment of a latent infection by CMV, which if completely quiescent at the level of viral gene expression would represent an ultimate in immune evasion strategies, is not sufficient for lifelong persistence and dissemination of the virus. CMV needs to reactivate and replicate in a lytic cycle of infection in order to disseminate further, which occurs in the face of a fully primed secondary immune response...

PURPOSE OF REVIEW: In the process of bone fracture healing, inflammation is thought to be an essential process that precedes bone formation and remodeling. We review recent studies on bone fracture healing from an osteoimmunological point of view. RECENT FINDINGS: Based on previous observations that many types of immune cells infiltrate into the bone injury site and release a variety of molecules, recent studies have addressed the roles of specific immune cell subsets...

CNS myelination defects occur in mice deficient in receptor-like protein tyrosine phosphatase alpha (PTPα). Here, we investigated the role of PTPα in oligodendrocyte differentiation and myelination using cells and tissues from wild-type (WT) and PTPα knockout (KO) mice. PTPα promoted the timely differentiation of neural stem cell-derived oligodendrocyte progenitor cells (OPCs). Compared to WT OPCs, KO OPC cultures had more NG2+ progenitors, fewer myelin basic protein (MBP)+ oligodendrocytes, and reduced morphological complexity...

BACKGROUND/AIM: Medulloblastoma (MBL), an archetypal primitive neuroectodermal tumor of the cerebellum, is the most common pediatric central nervous system malignancy representing approximately 20% of all childhood brain tumors. Herein, we report on a new xenotransplantable tumor cell line, derived from a 6-year-old female patient with cerebellar medulloblastoma, and the completele proteome molecular characterization of subsequent tumors from MBL xenotrasplanted mice. MATERIALS AND METHODS: Tumors were grown in nude mice as subcutaneous xenografts (MBLX) composed of small round cells with hyperchromatic nuclei and scant cytoplasm...

We investigated the functional role and clinical significance of Stearoyl CoA desaturase-1 (SCD1) mediated endoplasmic reticulum (ER) stress in regulation of liver tumor-initiating cells (T-ICs) and sorafenib resistance, aiming to develop a novel therapeutic strategy against hepatocellular carcinomas (HCCs) METHODS We evaluated the clinic-pathological relevance of SCD1 and its correlation with sorafenib resistance in large cohorts of HCC clinical samples by qPCR and immunohistochemical analyses. Lentiviral-based overexpression and knockdown approaches were performed to characterize functional roles of SCD1 in regulation of liver T-ICs and sorafenib resistance...

Unique immunologic adaptations exist to successfully establish and maintain pregnancy and to avoid an immune attack against the semi allogenic fetus. These adaptations occur both locally at the maternofetal interface and in the peripheral circulation and affect the innate as well as the adaptive immune system. Pregnancy is characterized by a general inflammatory state with activation of monocytes and granulocytes, but also with suppressive lymphocytes (regulatory T cells), and skewing towards T helper 2 immunity...

BACKGROUND: Primary lymphedemas are constitutional abnormalities of the lymphatic system. Secondary lymphedemas occur after damage to the lymphatic system, mainly after cancer treatments or tumour mass compression. There are many other causes, including filariasis, which is nonetheless very rare in France. PATIENTS AND METHODS: A 52-year-old man presented with a two-month history of increased size of the left leg. He was asymptomatic and in good general condition...

Pemphigus is a skin and mucosal membrane-targeting autoimmune bullous disease. Previous studies have demonstrated that circulating anti-desmoglein1/3 antibodies are pathogenic and mediate blister formation. However, the role of infiltrated immune cells in the lesional skin has not been fully investigated. In this study we showed that there existed a large number of B, T lymphocytes and plasma cells in the skin lesions by immunohistochemistry and immunofluorescence staining. In addition, a significantly increased number of Dsg1 and Dsg3-specific B cells could be identified by flow cytometric analysis or ELISPOT assay...

On acquisition of an oncogenic mutation, primary human and mouse cells can enter oncogene-induced senescence (OIS). OIS is characterized by a stable proliferation arrest and secretion of pro-inflammatory cytokines and chemokines, the senescence-associated secretory phenotype (SASP). Proliferation arrest and the SASP collaborate to enact tumor suppression, the former by blocking cell proliferation and the latter by recruiting immune cells to clear damaged cells. However, the interactions of OIS cells with the immune system are still poorly defined...

AIMS: The aim of the present work was to prepare, characterize, and evaluate proliposomes containing lipophilic prodrug ritonavir for targeting towards CD4+ T cells in the lymphatic system. MATERIALS AND METHODS: The liposomes were prepared by lipid thin film hydration method and lyophilized in the presence of cryoprotectant mannitol to obtain proliposomes. The optimized proliposomes by Central Composite Design, were surface modified with biotin. The proliposomes were evaluated for particle size, zeta potential, polydispersity index (PDI), entrapment efficiency, in vitro drug release, in vivo pharmacokinetics and biodistribution studies...
