[Transmission of antibodies from mother to offspring: evolutionary aspects]

BAINTNER Károly

[The earliest known form of transmission of antibody is the transport from the maternal circulation into the yolk during vitellogenesis (in birds and reptiles), followed by endodermal uptake and transport into the embryonal circulation. During the early mammalian evolution lacteal secretion and the development of the placenta opened new ways to feed the young. These changes also resulted in alterations in sites and mechanisms of transmission of immunoglobulins. In a few species (e.g. rabbit and... tovább »

[Regulatory T cells in mixed connective tissue disease]

BARÁTH Sándor, ALEKSZA Magdolna, SZEGEDI Andrea, SIPKA Sándor, SZEGEDI Gyula, BODOLAY Edit

[INTRODUCTION - CD4+/CD25+high suppressor and IL-10 producing CD4+ regulatory T (IL-10 Treg) cells were investigated in the peripheral blood of 48 patients with mixed connective tissue disease (MCTD). Seventeen patients were in active and 31 patients in inactive state. PATIENTS AND METHODS - Measurement of the number of CD4+CD25+high suppressor and IL-10 Treg cells was carried out by flow cytometry. RESULTS - The absolute number and percent of CD4+CD25+high T cells decreased in MCTD patients... tovább »

[Extensive flow cytometric characterization of plasmocytoid dendritic cell leukemia cells]

GOPCSA László, KORMOS Luca, BÁNYAI Anikó, TAMÁSKA Júlia, MATOLCSY András, GOGOLÁK Péter, RAJNAVÖLGYI Éva, PÁLÓCZI Katalin

[INTRODUCTION - Accumulating evidences suggest that non-T, non-B cell CD4+/CD56+ neoplasms with lymphoblastic morphology include clinically and immunophenotypically diverse entities. Although their cells of origin or classification are still controversial several entities clearly represent a distinct type of neoplasms that are clinically aggressive. CASE REPORT - In this work we present the immunophenotypic and genotypic features of bone marrow, peripheral blood, lymph node and skin lymphocytes... tovább »

[Plasmacytoid dendritic cells - type I interferon producing cells]

MAGYARICS Zoltán, RAJNAVÖLGYI Éva

[Dendritic cells represent a multifunctional cell population classified to myeloid (mDC) and plasmacytoid (pDC) types. Both subsets circulate in the peripheral blood and are found in lymphoid and also in non-lymphoid tissues, where they act as sensors of environmental changes. Upon activation by a wide range of stimuli they undergo morphological and functional transition and give rise to professional antigen presenting cells, which migrate to lymphoid organs. A newly identified precursor subset... tovább »
