Rab GTPases Regulating Phagosome Maturation Are Differentially Recruited to Mycobacterial Phagosomes [PDF]
Traffic, 2011 Mycobacterium tuberculosis (M. tb) is an intracellular pathogen that can replicate within infected macrophages. The ability of M. tb to arrest phagosome maturation is believed to facilitate its intracellular multiplication. Rab GTPases regulate membrane trafficking, but details of how Rab GTPases regulate phagosome maturation and how M ...

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells
Advanced Materials, EarlyView.This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

The ectodomain of Toll-like receptor 9 is cleaved to generate a functional receptor. [PDF]
, 2008 Mammalian Toll-like receptors (TLRs) 3, 7, 8 and 9 initiate immune responses to infection by recognizing microbial nucleic acids; however, these responses come at the cost of potential autoimmunity owing to inappropriate recognition of self nucleic acids.

Advanced Science, EarlyView.Normal bladders exhibit quiescent fibroblasts/macrophages, whereas neurogenic bladders show acute‐phase Itga8⁺ fibroblast expansion driven by Trem2⁺ macrophage‐secreted Fn1, which activates FAK/RhoA/ROCK signaling, promotes cytoskeletal remodeling, and upregulates pro‐fibrotic genes.

European Journal of Cell Biology, 2021 Phagocytosis consists in ingestion and digestion of large particles, a process strictly dependent on actin re-organization. Using synchronized phagocytosis of IgG-coated latex beads (IgG-LB), zymosan or serum opsonized-zymosan, we report the formation of

Interaction of mycobacterium tuberculosis with the host cells: a focus in the molecular mechanism involved in trafficking and autophagy [PDF]
, 2018 Tuberculosis (TB) is an ancient disease remaining a serious health threat worldwide. It is caused by Mycobacterium tuberculosis (Mtb), an acid-fast bacilli, non-sporulated, slow-growing, immobile and aerobic.

Advanced Science, EarlyView.Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

Comparison of the kinetics of maturation of phagosomes containing apoptotic cells and IgG-opsonized particles. [PDF]
PLoS ONE, 2012 Defective clearance of apoptotic cells has emerged as an important contributing factor to the pathogenesis of many diseases. Although many efforts have been made to understand the machinery involved in the recognition between phagocytes and potential ...

Effects of cyclic adenosine 3,5-monophosphate on photoreceptor disc shedding and retinomotor movement. Inhibition of rod shedding and stimulation of cone elongation. [PDF]
, 1982 As a test of the hypothesis that cyclic nucleotides play a role in the regulation of retinomotor movements and disc shedding in the photoreceptor-pigment epithelial complex, we have used an in vitro eyecup preparation that sustains both disc shedding and
