Plasma membrane rupture (PMR) is the final cataclysmic event in lytic cell death. PMR releases intracellular molecules termed damage-associated molecular patterns (DAMPs) that propagate the inflammatory response1–3. The underlying mechanism for PMR, however, is unknown. Here we show that the ill-characterized nerve injury-induced protein 1 (NINJ1)4–8 — a cell surface protein with two transmembrane

Dopamine-based mechanism for transient forgetting Nature (IF 42.778) Pub Date : 2021-01-20 John Martin Sabandal; Jacob A. Berry; Ronald L. Davis
Active forgetting is an essential component of the memory management system of the brain1. Forgetting can be permanent, in which prior memory is lost completely, or transient, in which memory exists in a temporary state of impaired retrieval. Temporary blocks on memory seem to be universal, and can disrupt an individual’s plans, social interactions and ability to make rapid, flexible and appropriate

In dynamic environments, subjects often integrate multiple samples of a signal and combine them to reach a categorical judgment1. The process of deliberation can be described by a time-varying decision variable (DV), decoded from neural population activity, that predicts a subject’s upcoming decision2. Within single trials, however, there are large moment-to-moment fluctuations in the DV, the behavioural

Hutchinson–Gilford progeria syndrome (HGPS or progeria) is typically caused by a dominant-negative C•G-to-T•A mutation (c.1824 C>T; p.G608G) in LMNA, the gene that encodes nuclear lamin A. This mutation causes RNA mis-splicing that produces progerin, a toxic protein that induces rapid ageing and shortens the lifespan of children with progeria to approximately 14 years1,2,3,4.

Landau quantization and highly mobile fermions in an insulator Nature (IF 42.778) Pub Date : 2021-01-04 Pengjie Wang; Guo Yu; Yanyu Jia; Michael Onyszczak; F. Alexandre Cevallos; Shiming Lei; Sebastian Klemenz; Kenji Watanabe; Takashi Taniguchi; Robert J. Cava; Leslie M. Schoop; Sanfeng Wu
In strongly correlated materials, quasiparticle excitations can carry fractional quantum numbers. An intriguing possibility is the formation of fractionalized, charge-neutral fermions—for example, spinons1 and fermionic excitons2,3—that result in neutral Fermi surfaces and Landau quantization4,5 in an insulator. Although previous experiments in quantum spin liquids1, topological Kondo insulators6,7

Pairing of segmentation clock genes drives robust pattern formation Nature (IF 42.778) Pub Date : 2020-12-23 Oriana Q. H. Zinani; Kemal Keseroğlu; Ahmet Ay; Ertuğrul M. Özbudak
Gene expression is an inherently stochastic process1,2; however, organismal development and homeostasis require cells to coordinate the spatiotemporal expression of large sets of genes. In metazoans, pairs of co-expressed genes often reside in the same chromosomal neighbourhood, with gene pairs representing 10 to 50% of all genes, depending on the species3,4,5,6. Because shared upstream regulators
