Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

open access: yesFEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

Cell surface CD11c as a neutrophil aging marker molecule

open access: yesFEBS Open Bio, EarlyView.
Cell surface CD11chi neutrophils were more aged and had better phagocytic function than CD11c−/lo neutrophils. Transcriptomic analysis of CD11chi neutrophils and CD11c−/lo neutrophils in pediatric population showed that the most difference was seen in infants.

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

In vitro generation of regulatory T cells: A challenging tool for studying immune aging in humans

open access: yesFEBS Open Bio, EarlyView.
In vitro induction of human regulatory T cells using standard protocols generates suppressive, Foxp3‐expressing CD4+ T cells independently of TGF‐β supplementation and donor age. Regulatory T (Treg) cells play a key role in immune tolerance and homeostasis.

Host plant use and possibly defensive horns in Trichochermes magna (Psilidae: Homoptera)

open access: yesRevista de Biología Tropical, 1998
En un muestreo hecho de febrero a junio en Puntarenas, Costa Rica, cuatro de 20 árboles de Psedolmedia oxphylaría (Moraceae) tenían agallas del insecto Trichochermes magma. Un 7% de las agallas mostraban signos de parasitación o depredación.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
