Quantifying Drosophila melanogaster Eye Phenotypes: A Computational Approach Integrating ilastik and Flynotyper.

The Drosophila melanogaster compound eye is a well-structured and comprehensive array of around 800 ommatidia, exhibiting a symmetrical and hexagonal pattern. This regularity and ease of observation make the Drosophila eye system a powerful tool to model various human neurodegenerative diseases. However, ways of quantifying abnormal phenotypes, such as manual ranking of eye severity scores, have limitations, especially when ranking weak alterations in eye morphology.

Endogenously produced itaconate negatively regulates innate-driven cytokine production and drives global ubiquitination in human macrophages.

A wide variety of electrophilic derivatives of itaconate, the Kreb's cycle-derived metabolite, are immunomodulatory, yet these derivatives have overlapping and sometimes contradictory activities. Therefore, we generated a genetic system to interrogate the immunomodulatory functions of endogenously produced itaconate in human macrophages. Endogenous itaconate is driven by multiple innate signals restraining inflammatory cytokine production.

SHIP1 modulation and proteome characterization of microglia.

Understanding microglial states in the aging brain has become crucial, especially with the discovery of numerous Alzheimer's disease (AD) risk and protective variants in genes such as INPP5D and TREM2, which are essential to microglia function in AD. Here we present a thorough examination of microglia-like cells and primary mouse microglia at the proteome and transcriptome levels to illuminate the roles these genes and the proteins they encode play in various cell states. First, we compared the proteome profiles of wildtype and INPP5D (SHIP1) knockout primary microglia.

The Cost of Biotech Innovation: Exploring Research and Development Costs of Cell and Gene Therapies.

Background: Clinical development paradigms for cell and gene therapies appear to be different to those of more conventional treatments: therefore, it is informative to explore this from the perspective of investments required to bring a new cell and/or gene therapy to the market. While there are a number of studies in the literature analyzing clinical-stage R&D costs for novel therapeutics, these are 'modality-agnostic' and thus do not elucidate costs specifically for the emerging class of cell and gene therapies.

Objectives: The objective of this study was to understand the research and development (R&D) costs associated with the clinical development of new cell and gene therapy assets METHODS: As part of our analysis of clinical-stage R&D costs for cell and gene therapies, we focused our efforts on cell and gene therapy assets recently approved by the US Food and Drug Administration (FDA) or expected to receive FDA approval by the end of 2024.

Eip74EF is a dominant modifier for ALS-FTD-linked VCP phenotypes in the Drosophila eye model.

Objectives: In 2012, Liu et al. reported that miR-34 is an age-related miRNA regulating age-associated events and long-term brain integrity in Drosophila. They demonstrated that modulating miR-34 and its downstream target, Eip74EF, showed beneficial effects on an age-related disease using a Drosophila model of Spinocerebellar ataxia type 3 expressing SCA3trQ78.
