Sensing of cytosolic LPS through caspy2 pyrin domain mediates noncanonical inflammasome activation in zebrafish

open access: yesNature Communications, 2018
In humans, caspase-5 is an LPS sensor that can induce gasdermin D cleavage and pyroptosis. Here, the authors show that zebrafish caspy2 is a functional homolog as it also senses cytosolic LPS to activate the noncanonical inflammasome and to protect ...

Efficient generation of male germ-like cells derived during co-culturing of adipose-derived mesenchymal stem cells with Sertoli cells under retinoic acid and testosterone induction

open access: yesStem Cell Research & Therapy, 2019
Background Adipose-derived mesenchymal stem cells (ADMSCs) are considered an efficient and important candidate for male infertility treatment because they contain pluripotent stem cells, which can differentiate into all cells from three germ layers ...

Dynamic response of Aspergillus niger to single pulses of glucose with high and low concentrations

open access: yesBioresources and Bioprocessing, 2019
Microorganisms generally encounter a fluctuating environment in their natural habitat and similar conditions also happen in large-scale bioreactors. In this work, the dynamic response of intracellular and extracellular metabolites of Aspergillus niger ...

Two strategies to improve the supply of PKS extender units for ansamitocin P-3 biosynthesis by CRISPR–Cas9

open access: yesBioresources and Bioprocessing, 2022
Ansamitocin P-3 (AP-3) produced by Actinosynnema pretiosum is a potent antitumor agent. However, lack of efficient genome editing tools greatly hinders the AP-3 overproduction in A. pretiosum.

Enhancing mesenchymal stem cells cultivated on microcarriers in spinner flasks via impeller design optimization for aggregated suspensions

open access: yesBioresources and Bioprocessing, 2023
During the ex vivo expansion of umbilical cord-derived mesenchymal stem cells (hUCMSCs) in a stirred tank bioreactor, the formation of cell–microcarrier aggregates significantly affects cell proliferation and physiological activity, making it difficult ...

Operation of a Benchtop Bioreactor [PDF]

open access: yesJournal of Visualized Experiments, 2013
Fermentation systems are used to provide an optimal growth environment for many different types of cell cultures. The ability afforded by fermentors to carefully control temperature, pH, and dissolved oxygen concentrations in particular makes them essential to efficient large scale growth and expression of fermentation products. This video will briefly

FLOCCULATION BIOREACTORS [PDF]

open access: yes, 2010
One of the main goals of bioprocess engineering is to increase the productivity of biotechnological processes and a vigorous progress has been observed in that field over the last decades. Fermentation based processes are not an exception and, in order to achieve those objectives, techniques such as the use of high cell density systems have been ...

Plant Bioreactors for Pharmaceuticals [PDF]

open access: yesBiotechnology and Genetic Engineering Reviews, 2008
Plant bioreactors are attractive expression systems for economic production of pharmaceuticals. Various plant expression systems or platforms have been tested with certain degrees of success over the past years. However, further development and improvement are needed for more effective plant bioreactors.
