Regulation of Antigen Export to the Cytosol During Cross-Presentation
Frontiers in Immunology, 2019 Cross-priming refers to the induction of primary cytotoxic CD8+ T cell responses to antigens that are not expressed in antigen presenting cells (APCs) responsible for T cell priming.

Heat-Induced Oxidation of the Nuclei and Cytosol
Frontiers in Plant Science, 2021 The concept that heat stress (HS) causes a large accumulation of reactive oxygen species (ROS) is widely accepted. However, the intracellular compartmentation of ROS accumulation has been poorly characterized.

Cytosolic cysteine in redox signaling [PDF]
Plant Signaling & Behavior, 2008 CYSTEINE BIOSYNTHESIS IN PLANTS TAKES PLACE IN THE THREE CELLULAR COMPARTMENTS WITH AUTONOMOUS PROTEIN BIOSYNTHESIS MACHINERY: cytosol, plastids and mitochondria. This sulfur-containing molecule is synthesized sequentially in these compartments by two enzymatic families, the serine acetyltransferases and the O-acetylserine(thiol) lyases.

Regeneration of cytosolic thiol peroxidases
Physiologia Plantarum, 2023 AbstractThree soluble type two peroxiredoxins (PRXIIB, C, D) and two glutathione peroxidase‐like enzymes (GPXL2, 8) reside in the cytosol of Arabidopsis thaliana cells and function both as thiol‐dependent antioxidants and redox sensors. Their primary substrate is H2O2, but they also accept other peroxides with a distinct preference between PRXII and ...

Acta Societatis Botanicorum Poloniae, 2014 Three forms of glutamate synthase (NADH-GOGAT, NADPH-GOGAT and Fd-(ferredoxin) GOGAT) were found in the plastids and cytosol of Pisum arvense root cells.

Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance By studying in vivo changes of ATP levels in the plastids and cytosol of Arabidopsis thaliana using a FRET-based ATP sensor, we show that the plastidic ATP concentrations in cotyledon, hypocotyl, and root of 10-day-old seedlings are ...

Emerging Roles of Long Noncoding RNAs in the Cytoplasmic Milieu
Non-Coding RNA, 2020 While the important functions of long noncoding RNAs (lncRNAs) in nuclear organization are well documented, their orchestrating and architectural roles in the cytoplasmic environment have long been underestimated.

RPA and Rad51 constitute a cell intrinsic mechanism to protect the cytosol from self DNA
Nature Communications, 2016 Immune recognition of cytosolic DNA represents a central antiviral defence mechanism. Within the host, short single-stranded DNA (ssDNA) continuously arises during the repair of DNA damage induced by endogenous and environmental genotoxic stress. Here we
