Simian virus 40 (SV40) large tumor antigen (Tag) represents a virus-encoded tumor-specific antigen expressed in many types of human cancers and a potential immunologic target for antitumor responses. Fc receptors are important mediators in the regulation and execution of host effector mechanisms against conditions including infectious diseases, autoimmunity, and cancer. By examining tumor prote...

Skin is complex and comprised of distinct layers, each layer with unique architecture and immunologic functions. Cells within these layers produce differing amounts of antimicrobial peptides and lipids (sphingoid bases and sebaceous fatty acids) that limit colonization of commensal and opportunistic microorganisms. Furthermore, antimicrobial peptides and lipids have distinct, concentration-depe...

The CD20-directed monoclonal antibody rituximab established a new era in lymphoma therapy. Since then other epitopes on the lymphoma surface have been identified as potential targets for monoclonal antibodies (mAb). While most mAbs eliminate lymphoma cells mainly by antibody-dependent cellular cytotoxicity, complement-dependent cytotoxicity or direct cell death, others counter mechanisms utiliz...

To identify cells with potential antileukemia activity following bone marrow transplantation. we have monitored immunologic reconstitution in a patient with acute lymphocytic leukemia in second remission who received intensive chemotherapy and total body irradiation followed by infusion of albogeneic histocompatible marrow. Prior to transplantation. donor bone marrow cells were depleted of T ly...

A novel vaccination strategy induced specific CD8(+) T cell-mediated immunity that eradicated spontaneous and experimental pulmonary cancer metastases in syngeneic mice and was also effective in a therapeutic setting of established breast cancer metastases. This was achieved by targeting transcription factor Fos-related antigen 1(Fra-1), overexpressed by many tumor cells, with an ubiquitinated ...

Introduction Treatment-free remission (TFR) in patients with chronic myeloid leukemia phase is considered a safe option if suitable molecular monitoring available. However, the question arises as to which factors can contribute maintenance of TFR, and immunologic surveillance remaining leukemic cells believed be one them. Argentina Stop Trial an open-label, single-arm, multicenter trial assessi...

cow’s milk allergy (cma) is the most frequent food allergy in children and oral immunotherapy (oit) is a promising approach for treatment of patients. the most challenging cases are anaphylactic with coexisting asthma and proposing safe protocols is crucial especially in high risk groups. considering that cma varies among patients, an individualized oit protocol would be beneficial to achieve a...

Familial hemophagocytic lymphohistiocytosis (HLH) is a rare primary immunodeficiency disorder characterized by defects in cell-mediated cytotoxicity that results in fever, hepatosplenomegaly, and cytopenias. Familial HLH is well recognized in children but rarely diagnosed in adults. We conducted a retrospective review of genetic and immunologic test results in patients who developed HLH in adul...

background and objective: presence of hepatitis b core antibody (anti-hbc) in the absence of hepatitis b surface antigen (hbsag) and hepatitis b surface antibody (anti-hbs) is defined, as isolated anti-hbc. little is known about the clinical significance of the isolated anti-hbc in hepatitis b virus (hbv) infections. the aim of this study was to assess the significance of anti-hbc as the only m...
