Dorsolateral prefrontal cortex (DLPFCx) has been implicated in pain perception and in a pain modulation pathway. However, the precise participation of this region is not completely understood. The aim of this study was to evaluate whether 1 Hz rTMS of DLPFCx modifies threshold and tolerance in experimental pain. The effect of 1 Hz rTMS during 15 min at 100%(More)
Cytotoxic T-Lymphocye Antigen 4 (CTLA-4) or CD152 is an inhibitory molecule that plays a critical role in maintenance of tolerance to self-antigens. CTLA-4 is structurally as well as functionally related to CD28, since it shares 31% of homology and binds the B7 family molecules CD80 and CD86 with higher affinity. Nevertheless, CTLA-4 has opposing effects on(More)
Follicular helper T cells (T(FH)) have been implicated as a lineage that provides sufficient help to B cells in order to become professional antibody producers. This T helper subset is characterized by a distinctive cell-surface phenotype (CD4(+)CD57(+)CXCR5(+)) and cytokine profile (IL-21, IL-6, and IL-27) as well as transcriptional program (BCL-6, ICOS,(More)
BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is a well-known but rare complication in patients (<1%) with systemic lupus erythematosus (SLE). However, current epidemiological data are quite scant. The aim of the present study was to describe potentially unrecognised risk factors. PATIENTS AND METHODS We performed a multicentre,(More)
OBJECTIVE To analyze whether the expression and modulation of T cell receptor (TCR) signaling is dependent on Casitas B lineage lymphoma b (Cbl-b) in T cells from patients with systemic lupus erythematosus (SLE) upon stimulation with a tolerogenic substance. METHODS Peripheral blood mononuclear cells were obtained from 20 patients with SLE (active disease(More)
BACKGROUND Diagnosis of coronary artery disease (CAD) in patients with left bundle branch block (LBBB) is considered a challenge in cardiology due to low accuracy of noninvasive methods such as basal and exercise stress test. Recently, myocardial perfusion imaging showed attainment of higher sensitivity and specificity. Scintigraphy with thallium-201 has(More)
INTRODUCTION The association of thrombotic thrombocytopenic purpura (TTP) with systemic lupus erythematosus (SLE) is rare. It is associated with high morbidity and mortality. Information about risk factors and clinical outcomes is scant. MATERIAL AND METHODS A retrospective case-control study was performed in a referral center in Mexico City between 1994(More)
Early Growth Response (EGR) zinc finger transcription factors are induced under diverse mitogenic signals on different cell types such as lymphocytes. Their genetic expression does not require de novo protein synthesis, which suggests its role as immediate response mediators between cell surface receptor signaling and gene expression regulation. EGR factors(More)
Diminished pain sensitivity in schizophrenia has been reported in clinical studies. While the role of antipsychotic medications as a cause of the decrease in pain perception has been questioned, little is known about neural pain processing in treated schizophrenia patients. The aim of this pilot study was to examine the blood oxygen level-dependent (BOLD)(More)
Abnormal production of interferon type I has been widely related to multiple autoimmune diseases, particularly systemic lupus erythematosus (SLE). It has been considered the molecular signature characterized by the overexpression of type I Interferon related genes in SLE patients. Among these, are the interferon regulatory factors (IRF). These transcription(More)
