Physicochemical surface changes on phagocytic cells during differentiation in relation to chemotaxis and phagocytosis

Advances in Experimental Medicine and Biology

Abstract

During cell differentiation induced by DMSO, the HL-60 cells exhibit certain surface alterations such as increased hydrophobic interaction. Similar changes have been observed in activated alveolar macrophages, and granulocytes exposed to chemoattractant in vivo and in vitro. Whether these surface changes are directly linked to the enhanced chemotactic, oxidative and phagocytic responsiveness is unclear, although increased liability to hydrophobic interaction promotes phagocytic recognition in several systems. From the present data it is evident that oxidative and phagocytic responsiveness are acquired at different stages of differentiation. Detecting physicochemical differences in the surface properties of the HL-60 cells during differentiation may furthermore provide a useful tool for studying subpopulations of cells during differentiation and activation.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.
