Rapid methods to extract DNA and RNA fromCryptococcus neoformans

Alessandro Bolano, Silvia Stinchi, Roberta Preziosi, Francesco Bistoni et autres

Extraction of nucleic acids from the pathogenic yeast Cryptococcus neoformans is normally hampered by a thick and resistant capsule, accounting for at least 70% of the whole cellular volume. This paper presents procedures based on mechanical cell breakage to extract DNA and …

Programmed granulocyte neutrophil death in patients at different stages of HIV infection

Franco Baldelli, Roberta Preziosi, Daniela Francisci, Carlo Tascini et autres

HIV infection is associated with the gradual depletion and impairment of CD4 T lymphocytes [1,2], monocyte-macrophages [3], as well as polymorphonuclear leukocytes (PMNL) [4–8]. In HIV-infected individuals an increased susceptibility to apoptosis of CD4 and CD8 T cells has been demonstrated: it …
