Abstract:
This study analysed the intracellular delivery capacity of insect derived pyrrhocoricin with a peptide cargo in Cryptosporidium parvum in vitro using fluorescence microscopy. Results revealed that pyrrhocoricin was capable of acting as a delivery vehicle in transducing peptides across the parasite cell membrane for multiple life-cycle stages. The successful transduction may aid in target validation and the delivery of future peptide-based drugs against this important human pathogen.

Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
