Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

ORF8 Breaks Genetic System of Macrophage to Escape Reproductive Immunity by Telomerase and NOS-Like System

open access: yes, 2023
There is evidence that SARS-CoV-2 ORF8 may block interferon, change endoplasmic reticulum stress, damage chromatin, cause apoptosis, and hurt the male reproductive system through nitric oxide (NO).

INFLUÊNCIA DA POLINIZAÇÃO E DA MORFOLOGIA FLORAL NA FRUTIFICAÇÃO DE VARIEDADES DE LARANJA-DOCE INFLUENCE OF POLLINATION AND FLORAL MORPHOLOGY ON FRUIT SETTING IN SWEET ORANGE VARIETIES

open access: yesScientia Agricola, 1999
A espécie de laranjas doces (Citrus sinensis [L.] osbeck) é citada como sendo autógama. No entanto a alogamia tem sido demonstrada pelo aumento da produção de frutos com o uso de polinizadores eficientes, assim como pela existência de bons ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

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.
