    A classic but very rare “Árpád-type”mollusc assemblage, representing the endemic fauna of the Late Miocene–Early Pliocene Lake Pannon, was discovered in Kozármisleny (near Pécs, southern Hungary). The fossils were collected from silt layers deposited in the shallow sublittoral zone of Lake Pannon, exposed in an 8–10 m high road cut. The assemblage contained some very rare species, including the type species of the genus Lymnocardium, L. haueri (M. HÖRNES). Palynological investigations from the same layers failed to yield age-diagnostic dinofl agellates, and pointed to a brackish – freshwater depositional environment and warm temperate climate

    Impact of aging on calcium influx and potassium channel characteristics of T lymphocytes.

    Adaptive immunity and T cell function are affected by aging. Calcium influx patterns, regulated by Kv1.3 and IKCa1 potassium channels, influence T cell activation. We aimed to compare calcium influx kinetics in CD8, Th1 and Th2 cells in human peripheral blood samples obtained from five different age groups (cord blood, 10-15 ys, 25-40 ys, 45-55 ys, 60-75 ys).We measured calcium influx using flow cytometry in samples treated with or without specific inhibitors of Kv1.3 and IKCa1 channels (MGTX and TRAM, respectively).Calcium influx was higher in Th1 cells of adults, however, its extent decreased again with aging. Importantly, these changes were not detected in Th2 cells, where the pattern of calcium influx kinetics is similar throughout all investigated age groups. MGTX had a more pronounced inhibitory effect on calcium influx in Th2 cells, while in Th1 cells the same was true for TRAM in the 25-40 ys and 45-55 ys groups. Calcium influx of CD8 cells were inhibited to a similar extent by both applied inhibitors in these groups, and had no effect in the elderly.Altered lymphocyte potassium channel inhibitory patterns, regulators of calcium influx kinetics, might contribute to the development of age-related changes of T cell function
