In multicellular organisms, an enormous number of cells die every day, because of stress, injury, infection, or natural turnover necessary for proper tissue homeostasis. In most of these events, cell death is orchestrated by the dying cell itself, a sort of cellular suicide called apoptosis. Malfunctioning of this death program at any stage...

Although B cell chronic lymphocytic leukemia (B-CLL) has been traditionally viewed as a tumor of virgin B cells, this notion has been recently questioned by data suggesting that a fraction of B-CLL derives from antigen experienced B cells. In order to further clarify the histogenetic derivation of this lymphoproliferation, we have analyzed the...

CTLA-4 is a key factor in regulating and maintaining self tolerance, providing a negative signal to the T cell and thus limiting immune responses. Several polymorphisms within the CTLA-4 gene have been associated with an increased risk of developing autoimmune diseases and, very recently, with susceptibility to human cancer. Acute lymphoblastic...

Background: The human SH3 domain Binding Glutamic acid Rich Like 3 (SH3BGRL3) gene is highly conserved in phylogeny and widely expressed in human tissues. However, its function is largely undetermined. The protein was found to be overexpressed in several tumors, and recent work suggested a possible relationship with EGFR family members. We...

The human TP53 locus, located on the short arm of chromosome 17, encodes a tumour suppressor protein which functions as a tetrameric transcription factor capable of regulating the expression of a plethora of target genes involved in cell cycle arrest, apoptosis, DNA repair, autophagy, and metabolism regulation. TP53 is the most commonly mutated...

In the present study, the complete sequences of the Ig H and L chain variable region genes of twelve RF+ B cell lines from two patients with RA were analyzed. Seven of the RF-producing B cells used VH3 family genes, four used VH4 genes, and one a VH1 gene. All but two of the cell lines expressing VH3 genes utilized different family members;...

Because of its role in the regulation of the cell cycle, DNA damage response, apoptosis, DNA repair, cell migration, autophagy, and cell metabolism, the TP53 tumor suppressor gene is a key player for cellular homeostasis. TP53 gene is mutated in more than 50% of human cancers, although its overall dysfunction may be even more frequent. TP53...

Objectives: To validate the predictive value on time to first treatment (TTFT) of AIPS-E and IPS-E evaluated in an independent cohort of newly diagnosed and non-referred Binet stage A CLL patients enrolled in the O-CLL1-GISL protocol (clinicaltrial.gov identifier: NCT00917540). Methods: A cohort of 292 newly diagnosed Binet A CLL cases has been...

Hypersensitivity pneumonitis (HP) is a diffuse interstitial lung disease (ILD) caused by the inhalation of a variety of antigens in susceptible individuals. Patients with fibrotic HP (fHP) may show histopathological and radiological manifestations similar to patients with idiopathic pulmonary fibrosis (usual interstitial pneumonia-like pattern...
