In the 1980s the importance of HER2 signalling to the aberrant behaviour of a subset of breast cancer cells was recognized for the first time and, consequently, a hitherto unknown subtype of breast cancer - HER2-positive (HER2+) breast cancer was identified. The development of the anti-HER2 class of drugs, first with trastuzumab, followed closely by lapatinib, pertuzumab, and T-DM1, has improved outcomes dramatically. Nevertheless, metastatic HER2+ breast cancer remains an incurable disease and new therapeutic options are needed...

Survival of the allogeneic pregnancy depends on the maintenance of immune tolerance to paternal alloantigens at the fetomaternal interface. Multiple localized mechanisms contribute to the fetal evasion from the mother's immune rejection as the fetus is exposed to a wide range of stimulatory substances such as maternal alloantigens, microbes and amniotic fluids. In this article, we demonstrate that CD71+ erythroid cells are expanded at the fetomaternal interface and in the periphery during pregnancy in both humans and mice...

Shenzheng Mo, Yongmei Hua
Hydrogen sulfide (H2 S), a gaseous signaling molecule produced by cystathionine γ-lyase (CSE) and cystathionine β-synthase (CBS), influences bone remodeling in many ways. Osteoclasts play an important role in bone remodeling during tooth movement induced by mechanical loading, which increases the rate of tooth movement. Recently, we found that osteoclasts could produce H2 S. However, whether H2 S modulates bone remodeling by affecting osteoclasts remains unclear. In this study, we found that CSE-H2 S was a dominant H2 S generating system in osteoclasts, while CBS did not generate H2 S...

The periodontal ligament (PDL) is highly ordered connective tissue located between the alveolar bone and cementum. An aligned and organized architecture is required for its physiological function. We applied micropatterning technology to arrange PDL cells in 10- or 20-μm-wide extracellular protein patterns. Cell and nuclear morphology, cytoskeleton, proliferation, differentiation, and matrix metalloproteinase system expression were investigated. Micropatterning clearly elongated PDL cells with a low cell-shape index and low spreading area...

A series of self-assembled binuclear complexes (1-4) of Pd2 L'2 L2 composition are prepared by combination of selected cis-protected palladium(II) component cis-PdL' with equimolar amount of the nonchelating bidentate ligand 1,3-bis((pyridine-4-yl)methyl)urea, L. The cis-protecting unit L' crafted in the complexes [Pd2 (L')2 (L)2 ](NO3 )4 , 1-4, are ethylenediamine (en), tetramethylethylenediamine (tmeda), 2,2'-bipyridine (bpy), and 1,10-phenanthroline (phen), respectively. Complexation of palladium(II) with the ligand L, however, resulted in the self-assembled trinuclear complex [Pd3 (L)6 ](NO3 )6 , 5, of Pd3 L6 composition...

BACKGROUND: Immune checkpoint regulators, cytotoxic T lymphocyte antigen 4 (CTLA-4) and the programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) have emerged as promising new targets for cancer therapeutics. While tumor expression of PD-L1 has been shown to have objective responses to anti-PD-L1 immunotherapies, the clinical implications of CTLA-4 expression in tumor cells or immune cells in the tumor microenvironment is still controversial. We investigated the expression of CTLA-4 and PD-L1 in human breast tumors and provided a scoring system for the systematic evaluation of CTLA-4 staining...

BACKGROUND/AIMS: Successful replantation of an avulsed tooth depends on the regeneration of periodontal ligament (PDL) attachment which is affected by the transport medium, dry time and storage time. Various storage media have been studied but the search for the optimum storage medium is still needed to determine the ideal material and storage time to maintain PDL cells. The aim of this study was to determine the ability of Custodiol® , coconut water from different stages of maturity and propolis as storage media for avulsed teeth by evaluating the viability of PDL cells for different time intervals...

Due to its extremely pleiotropic nature, the complex effects of IFN-γ exerted both on immune and non-immune cell types still remain only partially understood. The longstanding view of IFN-γ as being a predominantly inflammatory cytokine is constantly challenged by increasing demonstrations of its direct or indirect regulatory roles. Interferon-γ can exert tolerogenic effects on both innate and adaptive immune cell types, promoting tolerance of various antigen-presenting cells, and augmenting function and differentiation of regulatory T cells, respectively...

Background: Malignant gliomas are heterogeneous brain tumors with the potential for aggressive disease progression, as influenced by suppressive immunoediting. Given the success and enhanced potential of immune-checkpoint inhibitors in immunotherapy, we focused on the connections between genetic alterations affected by IDH1 mutations and immunological landscape changes and PDL-1 expression in gliomas. Methods: Paired surgically resected tumors from lower-grade gliomas (LGGs) and glioblastomas (GBM) were investigated, and a genetic analysis of patients' primary tumor samples culled from TCGA datasets was performed...

BACKGROUND: "Avoiding immune destruction" has recently been established as one of the hallmarks of cancer. The programmed cell death (PD)-1/programmed cell death-ligand (PD-L) 1 pathway is an important immunosuppression mechanism that allows cancer cells to escape host immunity. The present study investigated how the expressions of these immune checkpoint proteins affected responses to neo-adjuvant chemotherapy (NAC) in breast cancer. METHODS: A total of 177 patients with resectable early-stage breast cancer were treated with NAC...

Leishmania donovani ( L. donovani ) is a causative pathogen of potentially-fatal visceral leishmaniasis (VL). Therapeutic agents are available; however, their use is limited due to high cost, serious side effects, and development of antimicrobial resistance. Protective immunity against VL depends on CD4+ Th1 cell-mediated immunity. Studies have shown that progression of VL is due to exhaustion of T cells; however, the mechanism involved is not clearly understood. Here, we examined the role of PD1/PDL-1 in the pathogenesis of VL using murine model of VL...

Introduction: Basaloid follicular hamartoma (BFH) is a rare, benign neoplasm of the hair follicle, characterized by multiple brown papules involving the face, scalp, and trunk. It is described by multiple clinical forms, and can present as localized or generalized. Diagnosis is made histologically via biopsy, which is important in order to distinguish BFH from basal cell carcinoma (BCC) or other malignant epithelial neoplasms. Correct diagnosis allows for the avoidance of unnecessary surgeries to remove benign lesions...

An avulsed tooth should ideally be replanted as soon as possible. Periodontal ligament (PDL) cells may survive for a short time in dry storage or storage in some physiologic media, enabling healing with normal PDL.1,2 However, after delayed replantation, when the extra oral drying time is longer than 60 min, the cells of the PDL will not survive.2-8 Despite this, even after long periods of dry extra oral time, delayed replantation is recommended although these PDL cells are necrotic.9,10 In such teeth ankylosis and osseous replacement are unavoidable, and the tooth will be eventually lost...

Improved understanding of the immunomodulatory interactions between tumor cells and immune cells has led to new and promising systemic therapeutic approaches in the first- and second-line therapy of urological tumors. Particularly in the case of urothelial carcinoma, for the first time in 20 years, checkpoint inhibitors (PD-1 and PDL-1 inhibitors) provide well-tolerated therapy that achieves response rates of >20% that can be sustained over the long term. This review explains the approach of immunotherapy and summarizes the current phase III clinical situation on urothelial carcinoma and renal cell carcinoma...
