Conventional and Tropism-Modified High-Capacity Adenoviral Vectors Exhibit Similar Transduction Profiles in Human iPSC-Derived Retinal Organoids.

Viral vector delivery of gene therapy represents a promising approach for the treatment of numerous retinal diseases. Adeno-associated viral vectors (AAV) constitute the primary gene delivery platform; however, their limited cargo capacity restricts the delivery of several clinically relevant retinal genes. In this study, we explore the feasibility of employing high-capacity adenoviral vectors (HC-AdVs) as alternative delivery vehicles, which, with a capacity of up to 36 kb, can potentially accommodate all known retinal gene coding sequences.

Transcriptome immune-regulatory differences between leprosy patients and type 1 reaction patients, before onset of symptoms.

Leprosy is a chronic disease of the skin and peripheral nerves caused by Mycobacterium leprae. A major public health and clinical problem are leprosy reactions, which are inflammatory episodes that often contribute to nerve damage and disability. Type I reversal reactions (T1R) can occur after microbiological cure of leprosy and affect up to 50% of leprosy patients.

Trace Elements in Medicinal Metallomics.

This analytical mini-review focuses on the effects of trace elements, which includes Cu, Mn, Zn, and Se, as well as some rarer microelements, on the regulation of oxidative stress in the body and of certain diseases associated with it. Synergism and competition between certain microelements have been considered a hot topic in the applied molecular pharmacology of these specific bio-effects. Some ideas for further possible directions of research are expressed.

Spectrum of pathogenic variants and high prevalence of pathogenic variants in Russian patients with Bardet-Biedl syndrome.

Introduction: Bardet-Biedl syndrome is a rare condition characterized by obesity, retinitis pigmentosa, polydactyly, development delay, and structural kidney anomalies. This syndrome has an autosomal recessive type of inheritance. For the first time, molecular genetic testing has been provided for a large cohort of Russian patients with Bardet-Biedl syndrome.
