Descripción general
Calcium ionophore A23187 is a carboxylic acid antibiotic with weak in vitro activity against Gram-positive organisms. It increases the potential of divalent ions to cross biological membranes, thus it acts as an ionophore. Calcium ionophore A23187 specifically forms stable 2:1 complex with divalent cations, rendering these ions soluble in ordinary organic solvents. Since calcium ionophore A23187 is commonly used to increase intracellular Ca2+ levels in intact cells, it acts as an uncoupler of oxidative phosphorylation and an inhibitor of mitochondrial adenosine triphosphatase (ATPase) activity. Calcium Ionophore A23187 is a potent inducer of phosphorylation of Toxoplasma eukaryotic initiation factor-2α (eIF2α). It also induces apoptosis in mouse lymphoma cell line (S49)7 but also has been shown to block apoptosis in other systems, such as when interleukin-3 (IL-3) is withdrawn from IL-3-dependent cells. Calcium ionophore A23187 is widely used as artificial activating substances for human oocytes.

Aplicación
Calcium ionophore A23187 has been used:
- as an endoplasmic reticulum (ER) stress inducer to study its effect on the expression of the toxoplasma unfolded protein response (UPR) genes
- for the induction of the acrosome reaction
- in skeletal muscle sarcoplasmic reticulum Ca2+ ATPase (SERCA) activity assay
Ionophore highly selective for Ca2+. Potentiates responses to NMDA but not quisqualate. In cell culture, stimulates nitric oxide production by calmodulin-dependent constitutive nitric oxide synthase.

Anucleate platelets perform two fundamental processes, activation and apoptosis. We elaborated an approach for selective and concurrent stimulation of platelet apoptosis and/or activation, processes important in haemostasis and platelet clearance. Human platelets were treated with BH3 mimetic ABT-737, thrombin, calcium

TMEM16A and 16B work as Cl(-) channel, whereas 16F works as phospholipid scramblase. The function of other TMEM16 members is unknown. Using TMEM16F(-/-) cells, TMEM16C, 16D, 16F, 16G, and 16J were shown to be lipid scramblases. Some TMEM16 members are

Although platelets possess the hallmarks of apoptosis such as activation of caspases, cytochrome c release and depolarisation of the mitochondrial transmembrane potential (∆Ψm), their entire apoptotic-signalling pathway is not totally understood. Therefore we studied the expression of various apoptotic proteins

The cell plasma membrane is tightly coupled with the vital processes of apoptosis and activation. In the current study, we investigated exposure of the apoptosis marker phosphatidylserine (PS) and activation marker P-selectin (CD62) on the plasma membrane of anucleate platelets.

Hydrolase are enzymes that regulate diverse biological processes, including posttranslational protein modifications. Recent work identified four active serine hydrolases (ASHs) in Toxoplasma gondii as candidate depalmitoylases. However, only TgPPT1 (ASH1) has been confirmed to remove palmitate from proteins.
