FAIR in action: Brain-CODE - A neuroscience data sharing platform to accelerate brain research.

The effective sharing of health research data within the healthcare ecosystem can have tremendous impact on the advancement of disease understanding, prevention, treatment, and monitoring. By combining and reusing health research data, increasingly rich insights can be made about patients and populations that feed back into the health system resulting in more effective best practices and better patient outcomes. To achieve the promise of a learning health system, data needs to meet the FAIR principles of findability, accessibility, interoperability, and reusability.

Bacterial toxins can inhibit host cell autophagy through cAMP generation.

Autophagy plays a significant role in innate and adaptive immune responses to microbial infection. Some pathogenic bacteria have developed strategies to evade killing by host autophagy. These include the use of 'camouflage' proteins to block targeting to the autophagy pathway and the use of pore-forming toxins to block autophagosome maturation.

Mechanisms and consequences of bacterial targeting by the autophagy pathway.

Autophagy is a key component of our immune response to invading pathogens. Autophagic targeting of intracellular bacteria within vacuolar compartments or the cytosol helps to control bacterial replication in the host cell. The mechanism by which these invading pathogens are selectively targeted for degradation is of particular interest.

A role for diacylglycerol in antibacterial autophagy.

Antibacterial autophagy is understood to be a key cellular immune response to invading microbes. However, the mechanism(s) by which bacteria are selected as targets of autophagy remain unclear. We recently identified diacylglycerol as a novel signaling molecule that targets bacteria to the autophagy pathway, and show that it acts via protein kinase C activation.

Antibacterial autophagy occurs at PI(3)P-enriched domains of the endoplasmic reticulum and requires Rab1 GTPase.

Autophagy mediates the degradation of cytoplasmic components in eukaryotic cells and plays a key role in immunity. The mechanism of autophagosome formation is not clear. Here we examined two potential membrane sources for antibacterial autophagy: the ER and mitochondria.

A diacylglycerol-dependent signaling pathway contributes to regulation of antibacterial autophagy.

Autophagy mediates the degradation of cytoplasmic contents in the lysosome and plays a significant role in immunity. Lipid second messengers have previously been implicated in the regulation of autophagy. Here, we demonstrate a signaling role for diacylglycerol (DAG) in antibacterial autophagy.

Eating twice for the sake of immunity: a phagocytic receptor that activates autophagy.

The mechanism by which the cell responds to invading pathogens is an area of intense research. Joubert et al. (2009) have found that the phagocytic receptor CD46 is able to activate autophagy through a tripartite interaction between itself, a scaffold protein GOPC, and the autophagy inducer complex of Beclin1-VPS34.

The adaptor protein p62/SQSTM1 targets invading bacteria to the autophagy pathway.

Autophagy, a cellular degradative pathway, plays a key role in protecting the cytosol from bacterial colonization, but the mechanisms of bacterial recognition by this pathway are unclear. Autophagy is also known to degrade cargo tagged by ubiquitinated proteins, including aggregates of misfolded proteins, and peroxisomes. Autophagy of ubiquitinated cargo requires p62 (also known as SQSTM1), an adaptor protein with multiple protein-protein interaction domains, including a ubiquitin-associated (UBA) domain for ubiquitinated cargo binding and an LC3 interaction region (LIR) for binding the autophagy protein LC3.
