Delivery of nucleic acids with positively charged lipid nanoparticles ((+)NPs) is widely used as research reagents and potentially for therapeutics due to their ability to deliver nucleic acids into the cell cytoplasm. However, in most reports little attention has been made to their toxic effects. In the present study, we performed comprehensive analyses of(More)
Live mRNA detection allows real time monitoring of specific transcripts and genetic alterations. The main challenge of live genetic detection is overcoming the high background generated by unbound probes and reaching high level of specificity with minimal off target effects. The use of Fluorescence Resonance Energy Transfer (FRET) probes allows(More)
Modulating T cell function by down-regulating specific genes using RNA interference (RNAi) holds tremendous potential in advancing targeted therapies in many immune-related disorders including cancer, inflammation, autoimmunity, and viral infections. Hematopoietic cells, in general, and primary T lymphocytes, in particular, are notoriously hard to transfect(More)
Integrins are heterodimeric membrane glycoproteins composed of noncovalently associated α and β subunits. Integrins support cell attachment and migration on the surrounding extracellular matrix as well as mediate cell-cell interaction in physiological and pathological settings. Constant recycling of integrins from the plasma membrane to the endosome makes(More)
TAF4b is a cell type-specific subunit of the general transcription factor TFIID. Here, we show that TAF4b is highly expressed in embryonic stem cells (ESC) and is down-regulated upon differentiation. To examine the role of TAF4b in ESC, we applied a knockdown (KD) approach. TAF4b depletion is associated with morphological changes and reduced expression of(More)
