CYTOCHALASIN B [PDF]

open access: yesJournal of Cell Biology, 1972
Abstract Cytochalasin B (2 to 4 µg/ml) reversibly inhibits the chemotactic response of human and rabbit polymorphonuclear leukocytes to a bacterial chemotactic factor or to the complement derived factor, C5a. At lower concentrations (1 to 0.1 µg/ml or less) Cytochalasin B actually stimulates chemotaxis.

Dereplication of Cytochalasans and Octaketides in Cytotoxic Extracts of Endophytic Fungi from Casearia arborea (Salicaceae)

open access: yesMetabolites, 2022
Endophytes have been shown to be a source of novel drug prototypes. The Casearia genus is known for presenting cytotoxic clerodane diterpenes; however, there are few reports on secondary metabolites produced by its fungal microbiota. Thus, in the present

Effect of age and cytoskeletal elements on the indentation-dependent mechanical properties of chondrocytes. [PDF]

open access: yes, 2013
Articular cartilage chondrocytes are responsible for the synthesis, maintenance, and turnover of the extracellular matrix, metabolic processes that contribute to the mechanical properties of these cells.

Testing Strategies of the In Vitro Micronucleus Assay for the Genotoxicity Assessment of Nanomaterials in BEAS-2B Cells

open access: yesNanomaterials, 2021
The evaluation of the frequency of micronuclei (MN) is a broadly utilised approach in in vitro toxicity testing. Nevertheless, the specific properties of nanomaterials (NMs) give rise to concerns regarding the optimal methodological variants of the MN ...

Bacterial Engulfment Mechanism Is Strongly Conserved in Evolution Between Earthworm and Human Immune Cells

open access: yesFrontiers in Immunology, 2021
Invertebrates, including earthworms, are applied to study the evolutionarily conserved cellular immune processes. Earthworm immunocytes (so-called coelomocytes) are functionally similar to vertebrate myeloid cells and form the first line of defense ...

Cytoskeleton-disrupting agent cytochalasin B reduces oxidative stress caused by high glucose in the human arterial smooth muscle

open access: yesJournal of Pharmacological Sciences, 2020
The role of cytoskeleton dynamics in the oxidative stress toward human vasculature has been unclear. The current study examined whether the cytoskeleton-disrupting agent cytochalasin B reduces oxidative stress caused by high glucose in the human arterial

Phosphorylation of CLEC-2 is dependent on lipid rafts, actin polymerization,secondary mediators, and Rac [PDF]

open access: yes, 2010
The C-type lectin-like receptor 2 (CLEC-2)activates platelets through Src and Syk tyrosine kinases via a single cytoplasmic YxxL motif known as a hem immunoreceptor tyrosine-based activation motif (hemITAM).Here, we demonstrate using sucrose gradient ...

Bioactive Phenylalanine Derivatives and Cytochalasins from the Soft Coral-Derived Fungus, Aspergillus elegans

open access: yesMarine Drugs, 2013
One new phenylalanine derivative 4′-OMe-asperphenamate (1), along with one known phenylalanine derivative (2) and two new cytochalasins, aspochalasin A1 (3) and cytochalasin Z24 (4), as well as eight known cytochalasin analogues (5–12) were isolated from

Occurrence and a possible mechanism of penetration of natural killer cells into k562 target cells during the cytotoxic interaction [PDF]

open access: yes, 1995
The cytotoxic interaction between cloned human Natural Killer (NK) cells and K562 target cells was studied using confocal laser scanning microscopy (CLSM) and conventional fluorescence microscopy.

Recovery of aging-related size increase of skin epithelial cells: in vivo mouse and in vitro human study. [PDF]

open access: yesPLoS ONE, 2015
The size increase of skin epithelial cells during aging is well-known. Here we demonstrate that treatment of aging cells with cytochalasin B substantially decreases cell size.
