The origin and structural evolution of de novo genes in Drosophila

Kavli Affiliate: Li Zhao | Authors: Junhui Peng and Li Zhao | Summary: Although previously thought to be unlikely, recent studies have shown that de novo gene origination from previously non-genic sequences is a common mechanism for gene innovation in many species and taxa. These young genes provide a unique set of candidates to study […]

An engineered biosensor enables dynamic aspartate measurements in living cells

Kavli Affiliate: Timothy Brown | Authors: Kristian Davidsen, Jonathan S Marvin, Abhi Aggarwal, Timothy A Brown and Lucas B Sullivan | Summary: Intracellular levels of the amino acid aspartate are responsive to changes in metabolism in mammalian cells and can correspondingly alter cell function, highlighting the need for robust tools to measure aspartate abundance. However, […]

Population encoding of stimulus features along the visual hierarchy

Kavli Affiliate: Michael Stryker | Authors: Luciano Dyballa, Andra M Rudzite, Mahmood S Hoseini, Mishek Thapa, Michael P Stryker, Greg D Field and Steven W Zucker | Summary: The retina and primary visual cortex (V1) both exhibit diverse neural populations sensitive to diverse visual features. Yet it remains unclear how neural populations in each area […]

A Chicken Tapasin ortholog can chaperone empty HLA molecules independently of other peptide-loading components

Kavli Affiliate: Michael W. Young | Authors: Georgia F Papadaki, Claire H Woodward, Michael C Young, Trenton J Winters, George M Burslem and Nikolaos G Sgourakis | Summary: Human Tapasin (hTapasin) is the main chaperone of MHC-I molecules, enabling peptide loading and antigen repertoire optimization across HLA allotypes. However, it is restricted to the endoplasmic […]

HD mutation results in a dominant negative effect on HTT function

Kavli Affiliate: Ali H. Brivanlou | Authors: Tiago L Laundos, Shu Li, Eric Cheang, Riccardo De Santis, Francesco M Piccolo and Ali H. Brivanlou | Summary: Huntington’s disease (HD) remains an incurable and fatal neurodegenerative disease long after CAG-expansion mutation in the huntingtin gene (HTT) was identified as the cause. The underlying pathological mechanism, whether […]

Multi-night naturalistic cortico-basal recordings reveal mechanisms of NREM slow wave suppression and spontaneous awakenings in Parkinson’s disease

Kavli Affiliate: Philip Starr | Authors: Md Fahim Anjum, Clay Smyth, Derk-Jan Dijk, Philip Starr, Timothy Denison and Simon Little | Summary: Background: Sleep disturbance is a prevalent and highly disabling comorbidity in individuals with Parkinson’s disease (PD) that leads to worsening of daytime symptoms, accelerated disease progression and reduced quality of life. Objectives: We […]

Nucleus-Independent Transgenerational Small RNA Inheritance in C. elegans

Kavli Affiliate: Shai Shaham | Authors: Itai Rieger, Guy Weintraub, Itamar Lev, Kesem Goldstein, Dana Bar-Zvi, Sarit Anava, Hila Gingold, Shai Shaham and Oded Rechavi | Summary: Studies using C. elegans nematodes demonstrated that, against the dogma, animals can transmit epigenetic information transgenerationally. While it is now clear that in these worms ancestral RNA interference […]
