Previously documented sexual response patterns of gender-specificity among gynephilic men and gender-nonspecificity among gynephilic women could be explained by women responding more strongly to non-gendered aspects of sexual stimuli. Cues of attractiveness are known determinants of sexual decision-making, yet have not been directly tested as determinants of sexual response. The current study investigated the role of attractiveness cues in explaining gender-based patterns of sexual response.

We therefore aimed to untangle the role of CFH and its splice variant, factor H-like 1 (FHL-1), in ocular complement regulation derived from local versus circulating sources. We assessed the therapeutic efficacy of adeno-associated viruses (AAVs) expressing human FHL-1 and a truncated version of CFH (tCFH), which retains the functional N- and C-terminal ends of the CFH protein, in restoring the alternative complement pathway in Cfh-/- mouse eyes and plasma.

Currently, NDDs are not curable and treatment focuses on alleviating symptoms and halting disease progression. Phenotypic heterogeneity between individual NDD patients, lack of robust biomarkers, the limited translational potential of experimental models, and other factors have hampered drug development for the treatment of NDDs.

In preparation for a clinical gene therapy trial, we conducted dose range finding (DRF) studies with an AAV2 capsid with three surface tyrosine residues changed to phenylalanine (AAV2tYF) vector administered by subretinal injection in a naturally occurring -mutant canine model (XLPRA2) to compare two different human () transgenes and to establish a reasonable starting dose for a clinical trial. Different dose levels of two candidate vectors (0.

The vector contains a codon-optimized human RPGR cDNA () driven by a photoreceptor-specific promoter (G protein-coupled receptor kinase 1 [GRK1]), and is packaged in an AAV2 capsid variant with three surface tyrosine residues changed to phenylalanine (AAV2tYF). We conducted a toxicity and efficacy study of this vector administered by subretinal injection in the naturally occurring mutant (X-linked progressive retinal atrophy 2 [XLPRA2]) dog model.
