WebbAs possible nonspecific side effects, we observed that the EGF induced Ca2+ influx and fluid-phase pinocytosis were inhibited in A431 cells in the presence of mAb 2E9. We conclude, therefore, that the activation of the EGFR signal transduction cascade can occur completely through exclusive binding of EGF to the subclass of high affinity EGFR. Webb14 apr. 2024 · Phytates are a type of organophosphorus compound produced in terrestrial ecosystems by plants. In plant feeds, phytic acid and its salt form, phytate, account for 60%–80% of total phosphorus. Because phytate is a polyanionic molecule, it can chelate positively charged cations such as calcium, iron, and zinc. Due to its prevalence in …

Pinocytosis vs. Phagocytosis – Difference Wiki

WebbThe uptake of lipoproteins by macrophages is a critical step in the development of atherosclerotic lesions. Cultured monocyte-derived macrophages take up large amounts of native LDL by receptor-independent fluid-phase pinocytosis, either constitutively or in response to specific activating stimuli, depending on the macrophage phenotype. Webb8 apr. 2024 · Phagocytosis. Phagocytosis is a type of endocytosis that involves the uptake of large particles such as bacteria, dead cells, or other debris. This process occurs in specialized cells called phagocytes, which engulf and breakdown the particles. Phagocytosis is an important mechanism for immune defense and tissue remodeling. teachins u s amenashe

The cells are not interested in the water in the vesicles, but any solutes that might be brought in. As you can imagine, this is not a very efficient way of bringing materials into the cell because it is nonspecific and brings whatever is in the fluid into the cell.
