An Implantable Optogenetics‐Engineered Hydrogel for Amelioration of Rheumatoid Arthritis through Light‐Controlled Metabolic Reprogramming of Synovial Macrophages

Advanced Science, EarlyView.
An implantable hydrogel is designed to enable in situ and on‐demand secretion of GLP‐1 in synovium through blue light irradiation to activate GLP‐1R/HK2/VDAC1 pathway for upregulating tricarboxylic acid cycle and oxidative phosphorylation in macrophage, facilitating tissue repair and bone erosion recovery.

Mitochondrial SLC25A46 Rewires Fatty Acid Oxidation to Promote Cell Proliferation and Ferroptosis Evasion in Ovarian Cancer by Stabilizing CACT

Advanced Science, EarlyView.
Mitochondrial SLC25A46 is upregulated in ovarian cancer (OC) and correlates with poor prognosis. SLC25A46 stabilizes CACT to activate fatty acid oxidation, increasing ATP and NADPH production to drive cell proliferation and ferroptosis evasion. SLC25A46 silencing sensitizes OC cells to ferroptosis and carboplatin, offering a promising therapeutic ...

Lilrb4a Suppression Reprograms Microglia to Mitigate APOE4‐Associated Amyloid Plaques and Cerebral Amyloid Angiopathy in Association With a PPAR‐Linked Pro‐Clearance State

Advanced Science, EarlyView.
Targeting Lilrb4a in Apolipoprotein E4 (APOE4)‐associated Alzheimer's disease (AD) reprograms microglia toward a beneficial, phagocytic state. Genetic deletion or antisense inhibition of Lilrb4a suppresses p‐SHP2/NF‐κB/STAT1 signaling, restores PPAR‐linked lipid and energy metabolism, and reduces amyloid plaque burden and cerebral amyloid angiopathy ...

Optimization of B Cell Responses in Human Immune System Mice Through Organoid Based Screening

Advanced Science, EarlyView.
Human immune system (HIS) mice show limited B cell responses to immunization. Using HIS mouse spleen organoids, this study identifies cytokine combinations and innate immune signals that drive human B cell expansion, differentiation, and class‐switch. Applying these signals in vivo through temporal separation enables antigen‐specific IgG responses and ...

Improved transfection efficiency of cultured human cells [PDF]

Cell Biology International, 2003
AbstractWe simultaneously tested the transfection efficiency of NT2/D1 and HeLa cells with Lipofectamine™ (Life Technologies) and Effectene™ (Qiagen) transfection reagents using the pCH110 eukaryotic assay vector, which contains the lacZ reporter gene.

Transfection efficiency of lipoplexes for site-directed delivery [PDF]

Journal of Liposome Research, 2009
Targeted gene delivery is a promising strategy to cure disease on its basic level at the site of interest. The ultrastructure, internalization, and transfection efficiency of lipoplexes was investigated. We found that at a charge ratio (rho) of 4.0 lipoplexes had optimum characteristics for gene delivery in vitro. To decrease the size of lipoplexes, we

Enhancement of the efficiency of femtosecond optical transfection [PDF]

SPIE Proceedings, 2010
Cell transfection is the process in which extra cellular nucleic acids such as DNA, RNA, Si-RNA can be deliberately injected into the cytoplasm of the cell. This technique of cell transfection forms a central tool in the hands of a cell biologist to explore the mechanism within the cell.

Efficient Transfection Method for Primary Cells

Tissue Engineering, 2002
Transfection of primary cells and stem cells is a problem in the laboratory routine and further in tissue engineering and gene therapy. Most methods working effectively for cell lines in culture fail to transfect primary cells. Here we describe the use of the Nucleofector technology developed by amaxa biosystems. We were able to transfect primary human
