1. Precursor B-lineage acute lymphoblastic leukemia patients with aberrant natural killer cell and T cell - lineage antigen expression: experience from a tertiary cancer care center
Abstract Introduction Flow cytometric immunophenotyping (FCI) plays a major role in diagnosing hematologic malignancies. In patients diagnosed with precursor B-lineage acute lymphoblastic leukemia (B-ALL), expression of certain non-lineage/cross lineage antigens is of prognostic and cytogenetic relevance. There is a paucity of studies that have comprehensiv

2. Can natural killer cell activity help screen patients requiring a biopsy for the diagnosis of prostate cancer?
ABSTRACT Purpose To evaluate the usefulness of natural killer cell activity (NKA) in diagnosing prostate cancer (PC). Materials and Methods The medical records of patients who underwent transrectal prostate biopsy (TRBx) at Korea University Ansan Hospital between May 2017 and December 2017 were retrospectively reviewed. NKA levels were measured using NK

4. Aquios CL flow cytometer performance in the automated quantification of lymphocyte subpopulations
RESUMO A citometria de fluxo (CF) é uma ferramenta importante para diagnóstico, prognóstico e acompanhamento terapêutico de diversas neoplasias hematológicas. Além disso, possibilita a quantificação das subpopulações linfocitárias (SPL) para assistência diagnóstica e monitoramento das imunodeficiências primárias e adquiridas por meio das expre

5. Antioxidant and immunomodulatory activities of Oviductus ranae in mice
Oviductus ranae (OR) is a traditional Chinese medicine, which was first recorded in the Compendium of Materia Medica in the Ming Dynasty. OR contains high amounts of proteins and elicits therapeutic effects on neurasthenia, insomnia, and respiratory symptoms, which are related to oxidative stress and immunodeficiency. This study aimed to obtain the potential

6. Innate immunity and HPV: friends or foes
Most human papillomavirus infections are readily cleared by the host immune response. However, in some individuals, human papillomavirus can establish a persistent infection. The persistence of high-risk human papillomavirus infection is the major risk factor for cervical cancer development. These viruses have developed mechanisms to evade the host immune sy

7. Clinical presentation of hemophagocytic lymphohistiocytosis in adults is less typical than in children
OBJECTIVE: Hemophagocytic lymphohistiocytosis in adults is largely underdiagnosed. To improve the rate and accuracy of diagnosis in adults, the clinical and laboratory characteristics of hemophagocytic lymphohistiocytosis were analyzed in and compared between adults and children in a Chinese cohort. METHOD: Data from 50 hemophagocytic lymphohistiocytosis p

8. Oral chronic graft-versus-host disease: analysis of dendritic cells subpopulations
The graft-versus-host disease is the major cause of morbidity and mortality in patients who have undergone hematopoietic stem cell transplantation. Aiming at contributing to the understanding of the role of myeloid and plasmacytoid dendritic cells, and natural killer cells in chronic graft-versus-host disease, we examined biopsies of jugal mucosa of 26 patie

9. Características de atividade das células natural killer em pacientes com esclerose sistêmica
INTRODUÇÃO: Estudos têm relatado um aumento da expressão das células natural killer (NK) no sangue periférico de pacientes com esclerose sistêmica (ES). Essas células fazem parte da imunidade inata, reconhecendo células infectadas por meio dos receptores killer immunoglobulin-like receptor (KIR), que apresentam acentuado polimorfismo. Um novo modelo

10. Immunological characteristics of mesenchymal stem cells
Although bone marrow is the main source, mesenchymal stem cells have already been isolated from various other tissues, such as the liver, pancreas, adipose tissue, peripheral blood and dental pulp. These plastic adherent cells are morphologically similar to fibroblasts and have a high proliferative potential. This special group of cells possesses two essenti

11. Variantes do gene CD226 associadas com a susceptibilidade ao diabetes mellitus tipo 1 autoimune / CD226 gene variants associated with susceptibility to type 1, immune mediated, diabetes
Recently, Genome Wide Association (GWA) studies identified a new locus, 18q22, as a canditate to Type 1 A, or immune mediated diabetes (T1AD) susceptibility. This locus harbors the CD226 gene, responsible for encoding the leukocyte adhesion molecule (CD226) involved in cell adhesion, differentiation of naïve CD4+T cells, cytotoxicity induced by natural kill

12. Caracterização das células T Natural Killer de células mononucleares de sangue periférico em indivíduos de diferentes continentes / Characterization of T cells Natural Killer (NKT) cells in peripheral blood mononuclear cells of healthy individuals from different continents
As células T Natural Killer (NKT) são linfócitos que expressam o rearranjo V24V11 com TCR invariante e reconhecem glicolipídeos como o alfagalactosilceramida (-GalCer) apresentado no contexto da molécula MHC-não clássica chamada CD1d. As NKT são divididas em subgrupos distintos: os fenótipos CD4+ e CD4- em camundongos e humanos, e CD8+ e CD4-CD8- em
