Natural IgM inhibits gene transfer by adenovirus type 5 (Ad5) vectors. We show that polyreactive natural IgM antibodies bind to Ad5 and that inhibition of liver transduction by IgM depends on Kupffer cells. By manipulating IgM concentration in vivo, we demonstrate that IgM inhibits liver transduction in a concentration-dependent manner. We further show that differences in natural IgM between BA...
results pcslab is a weak promoter responding to come and its binding appears to be negative cooperative. although pcslab is partially controlled by comcde, it can respond to comcde regulation. supported by the obtained molecular evidence, cslab acts as a stabilizer of comcde signal on the patterns of its expression. conclusions pcslab is partially controlled by comcde. cslab is a stabilizer of ...
Transplantation of genetically modified hematopoietic stem cells (HSCs) is a promising therapeutic strategy for genetic diseases, HIV, and cancer. However, a barrier for clinical HSC gene therapy is the limited efficiency of gene delivery via lentiviral vectors (LVs) into HSCs. We show here that rapamycin, an allosteric inhibitor of the mammalian target of rapamycin complexes, facilitates highl...
It is challenging to genetically manipulate fat in adults. We demonstrate that intraperitoneal (i.p.) injection of an engineered adeno-associated virus (AAV) serotype Rec2 leads to high transduction of multiple visceral fat depots at a dose of 1 to 2 orders lower than commonly used doses for systemic gene delivery. To target adipose tissue, we develop a single AAV vector harboring two expressio...
BETA2/NeuroD, a basic helix-loop-helix transcription factor, is a key regulator of pancreatic islet morphogenesis and insulin gene transcription. Here we report for the first time that the BETA2/NeuroD protein can permeate several cells, including pancreatic islets, due to an arginine- and lysine-rich protein transduction domain sequence in its structure. The BETA2/NeuroD protein was transduced...
Though G-proteins have been implicated in the primary step of taste signal transduction, no direct demonstration has been done in insects. We show here that a G-protein gamma subunit, Ggamma1, is required for the signal transduction of sugar taste reception in Drosophila. The Ggamma1 gene is expressed mainly in one of the gustatory receptor neurons. Behavioral responses of the flies to sucrose ...
