Cellular uptake pathways and recipient cells

Cellular uptake pathways and recipient cells refer to the collective mechanisms, such as endocytosis, phagocytosis, and pinocytosis, by which cells internalize extracellular cargo (Doherty and McMahon, 2009, Nature). These processes are fundamental for maintaining cellular homeostasis, nutrient uptake, and responding to environmental signals (Conner and Schmid, 2003, Nature). Recipient cells are the specific biological entities that receive these materials, often determined by the expression of specific surface receptors that trigger internalization (Sahay et al., 2010, Nature Biotechnology). In the context of drug delivery, these pathways are exploited to transport therapeutic agents, including nanoparticles and nucleic acids, into target cells to treat various diseases (Behzadi et al., 2017, Chemical Society Reviews). Understanding the specific uptake route is vital for avoiding lysosomal degradation and ensuring the therapeutic reaches its intracellular site of action. However, because this term describes a broad set of biological activities rather than a single molecule, it is not considered a specific therapeutic target in the traditional sense.
