RIPK1-RIPK3-MLKL-Associated Necroptosis Drives Killing in Neutrophils.

Necroptosis is a pro-inflammatory cell death, which happens in the context of caspase-8 inhibition, allowing activation of the receptor interacting protein kinase 1-receptor interacting protein kinase 3-mixed lineage kinase domain-like (RIPK1-RIPK3-MLKL) axis. Recently, necroptosis has emerged as a key component of resistance against pathogens including infected macrophage by , the ethiologic agent of Visceral leishmaniasis (VL). VL is the most severe form of Leishmaniasis, characterized by systemic inflammation and neutropenia.

The potential impact of using a surfactant and an alcoholic co-surfactant on SRB activity during EOR.

Surfactants and co-surfactants play an important role in enhanced oil recovery for they improve petroleum solubility and reduce interfacial tensions between oil, water and the rock formation. Ethanol is receiving renewed attention as potential co-surfactant because of the negative results obtained with the use of salts and alkaline substances. Sulphate-reducing bacteria (SRB) can use surfactants and co-surfactants as carbon sources and, consequently, this can increase the biological accumulation of sulphide (souring).
