Validation of a double-color ELISpot assay of IFN-γ and IL-4 production in human peripheral blood mononuclear cells.

The Enzyme-Linked ImmunoSpot (ELISpot) assay detects cytokines secreted during T cell-specific immune responses against pathogens. As this assay has acquired importance in the clinical setting, standard bioanalytical evaluation of this method is required. Here, we describe a formal bioanalytical validation of a double-color ELISpot assay for the evaluation of IFN-γ and IL-4 released by T helper 1 and T helper 2 cells, respectively.

Update on Pregnancy Following Breast Cancer Diagnosis and Treatment.

Survivorship has become a crucial component in breast cancer care. For women who have not completed their family planning, conceiving at the end of anticancer treatments should not be discouraged but might be challenging. Oncofertility counseling should be offered at the time of diagnosis to all patients, in order to inform them about the potential treatment-induced gonadotoxicity as well as the available strategies for fertility preservation, thus allowing to increase the chances of a future pregnancy.

Clinical and laboratory characterization of patients with localized scleroderma and response to UVA-1 phototherapy: In vivo and in vitro skin models.

Background/purpose: Localized scleroderma (LS) is a rare disease leading to progressive hardening and induration of the skin and subcutaneous tissues. LS is responsive to UVA-1 phototherapy, though its exact mechanism of action dermal fibrosis is yet to be fully elucidated. We aimed to investigate the molecular changes induced by UVA-1 rays in human primary fibroblasts cultures.

UVA-1 phototherapy as adjuvant treatment for eosinophilic fasciitis: in vitro and in vivo functional characterization.

Introduction: Eosinophilic fasciitis (EF) is a rare autoimmune disease causing progressive induration of dermal, hypodermal, and muscularis fascia. The exact pathogenesis is yet to be fully understood, and a validated therapy protocol still lacks. We here aimed to realize a clinical-functional characterization of these patients.

How to Protect Ovarian Function before and during Chemotherapy?

A significant number of women receive a cancer diagnosis before their age of natural menopause. Among these patients, the most frequent neoplasms are breast cancer, gynecological, and hematological malignancies. Premature ovarian insufficiency and infertility are among the most feared short- to long-term consequences of anticancer treatments in premenopausal patients.

Extracellular matrix remodeling and inflammatory pathway in human endometrium: insights from uterine leiomyomas.

Objective: To compare the expression profiles of matrix metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of matrix metalloproteinases, TIMPs) in the endometrium of women with and without type 3 leiomyomas and to understand their relationship with inflammatory status.

Design: Molecular and in silico studies.

Setting: University hospital.

Expression of Matrix Metalloproteinases and Their Inhibitors in Endometrium: High Levels in Endometriotic Lesions.

Endometriosis is a condition defined as presence of endometrium outside of the uterine cavity. These endometrial cells are able to attach and invade the peritoneum or ovary, thus forming respectively the deep infiltrating endometriosis (DIE) and the ovarian endometrioma (OMA), the ectopic lesions feature of this pathology. Endometriotic cells display high invasiveness and share some features of malignancy with cancer cells.

Expression of Taste Receptor 2 Subtypes in Human Testis and Sperm.

Taste receptors (TASRs) are expressed not only in the oral cavity but also throughout the body, thus suggesting that they may play different roles in organ systems beyond the tongue. Recent studies showed the expression of several TASRs in mammalian testis and sperm, indicating an involvement of these receptors in male gametogenesis and fertility. This notion is supported by an impaired reproductive phenotype of mouse carrying targeted deletion of taste receptor genes, as well as by a significant correlation between human semen parameters and specific polymorphisms of taste receptor genes.

Increased expression of neurogenic factors in uterine fibroids.

Study Question: Are selective markers for the neuronal differentiation such as microtubule-associated protein 2 (MAP-2) and synaptophysin (SYP) as well as the nerve growth factor (NGF) expressed by fibroids, myometrium and eutopic endometrium?

Summary Answer: Neuronal markers NGF, MAP-2 and SYP are highly expressed in fibroids compared with matched myometrium, and this neurogenic pathway is upregulated by tumor necrosis factor (TNF) alpha in cultured smooth muscle cells (SMCs).

What Is Known Already: Uterine fibroids or leiomyomas are the most common benign tumors, accounting for approximately one-third of hysterectomies. The present trend is to improve the medical treatment avoiding surgery, also for fertility sparing; hence, the pathogenic mechanisms are investigated, aiming to develop new therapeutic strategy.

Matrix metalloproteinases and their inhibitors in human cumulus and granulosa cells as biomarkers for oocyte quality estimation.

Objective: To study the molecular profile of metalloproteinases and their tissue inhibitors in granulosa and cumulus cells in a subset of fertile and infertile women.

Design: Molecular study with granulosa and cumulus cells.

Setting: University hospital.

Impaired spermatogenesis in the twitcher mouse: A morphological evaluation from the seminiferous tubules to epididymal transit.

Unlabelled: Spermatogenesis is a complex process of proliferation and differentiation during male germ cell development whereby undifferentiated spermatogonial germ cells evolve into maturing spermatozoa. In this developmental process the interactions between different cell types are finely regulated, hence any disruption in these relationships leads to male infertility. The twitcher mouse, the murine model of Krabbe disease, is characterized by deficiency of galactosylceramidase, an enzyme also involved in the metabolism of the galactosyl-alkyl-acyl-glycerol, the precursor of sulfogalactosyl-alkyl-acyl-glycerol, the most abundant glycolipid in spermatozoa.
