    Abstract: In the present disclosure, doxycycline-inducible astrocyte-specific HIV Tat transgenic mice (iTat), a surrogate HAND model, were treated with PNU-125096, a positive allosteric modulator of α7 nicotinic acetylcholine receptor (α7 nAChR) and effects on Tat-induced behavioral impairments and neuropathologies were observed. This disclosure shows that PNU-125096 treatment significantly improved locomotor, learning and memory deficits of iTat mice while inhibited glial activation and increased PSD-95 expression in the cortex and hippocampus of iTat mice. α7 nAChR knockout eliminated the protective effects of PNU-125096 on iTat mice. In addition, inhibition of p38 phosphorylation by SB239063, a p38 MAPK-specific inhibitor, exacerbated Tat neurotoxicity in iTat mice. These findings demonstrated for the first time that α7 nAChR activation led to protection against HAND and suggest that α7 nAChR and PNU-125096 hold significant promise for development of therapeutics for HAND.

    Abstract: The present disclosure relates generally to compounds comprising oligonucleotides complementary to a cystic fibrosis transmembrane conductance regulator (CFTR) RNA transcript. Certain such compounds are useful for hybridizing to a CFTR RNA transcript, including but not limited to a CFTR RNA transcript in a cell. In certain embodiments, such hybridization results in modulation of splicing of the CFTR transcript. In certain embodiments, such compounds are used to treat one or more symptoms associated with Cystic Fibrosis.
