Machaerina ascendens (Cyperaceae), a rare new species from the far south-west of Western Australia, and a new combination for Schoenus abbreviatus Nees

We here describe Machaerina ascendens R.L.Barrett & K.L.Wilson as a new species from swamps within forests in the far south-west of Western Australia. The new species is readily identifiable by its scrambling habit and compressed, multi-noded culms, features which separate it from all other Australian species. The clearly distichous glumes, few hypogynous scales fused at the base into a ring and prominently stipitate nutlets are also unusual features in Machaerina Vahl. Machaerina ascendens is highly range-restricted by its specific habitat and appears to qualify for listing as Endangered. Study of all names applicable to the current concept of Machaerina revealed an earlier name for the eastern Australian species Machaerina nuda (Steud.) J.Kern, and a new combination is provided here for Schoenus abbreviatus Nees as Machaerina abbreviata (Nees) R.L.Barrett & K.L.Wilson

Cofilin Activation in Peripheral CD4 T Cells of HIV-1 Infected Patients: A Pilot Study

Cofilin is an actin-depolymerizing factor that regulates actin dynamics critical for T cell migration and T cell activation. In unstimulated resting CD4 T cells, cofilin exists largely as a phosphorylated inactive form. Previously, we demonstrated that during HIV-1 infection of resting CD4 T cells, the viral envelope-CXCR4 signaling activates cofilin to overcome the static cortical actin restriction. In this pilot study, we have extended this in vitro observation and examined cofilin phosphorylation in resting CD4 T cells purified from the peripheral blood of HIV-1-infected patients. Here, we report that the resting T cells from infected patients carry significantly higher levels of active cofilin, suggesting that these resting cells have been primed in vivo in cofilin activity to facilitate HIV-1 infection. HIV-1-mediated aberrant activation of cofilin may also lead to abnormalities in T cell migration and activation that could contribute to viral pathogenesis.Department of Defense (National Defense Science and Engineering Fellowship); National Institute of Allergy and Infectious Diseases (AI069981
