Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Molecular weaponry:diverse effectors delivered by the Type VI secretion system [PDF]

open access: yes, 2015
The Type VI secretion system is a widespread bacterial nanomachine, used to deliver toxins directly into eukaryotic or prokaryotic target cells. These secreted toxins, or effectors, act on diverse cellular targets, and their action provides the attacking

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

YscP, a key player in the type three secretion system of "Yersinia enterocolitica" [PDF]

open access: yes, 2005
The Yersinia injectisome needle has a constant length of around 60nm. Mutants affected in the yscP gene display abnormally long needles, suggesting that needle length is genetically controlled and that YscP is involved in this process. First, both N- and

Functional regulation and cross-talk of type III and type VI secretion systems in Salmonella

open access: yesVirulence
In Salmonella, the type III and type VI secretion systems (T3SS and T6SS) play critical roles in pathogenicity. The bacterium harbors two distinct T3SSs: T3SS-1, encoded by SPI-1, promotes host cell invasion, whereas T3SS-2 (located within SPI-2 ...

Type VI Secretion System Toxins Horizontally Shared between Marine Bacteria.

open access: yesPLoS Pathogens, 2015
The type VI secretion system (T6SS) is a widespread protein secretion apparatus used by Gram-negative bacteria to deliver toxic effector proteins into adjacent bacterial or host cells.

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Integrated regulation of the type III secretion system and other virulence determinants in Ralstonia solanacearum [PDF]

open access: yes, 2006
In many plant and animal bacterial pathogens, the Type III secretion system (TTSS) that directly translocates effector proteins into the eukaryotic host cells is essential for the development of disease.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Structure of a bacterial type IV secretion core complex at subnanometre resolution [PDF]

open access: yes, 2013
Type IV secretion (T4S) systems are able to transport DNAs and/or proteins through the membranes of bacteria. They form large multiprotein complexes consisting of 12 proteins termed VirB1-11 and VirD4.
