Application

Cyclosporin H has been used:
  • to pre-culture the lineage depleted murine Flt3ITDIDH2R140Q BM cells for transduction
  • as a formyl peptide receptor (FPR) antagonist to study the role of FPR1 in calcium mobilization in polymorphonuclear leukocytes (PMNs)
  • as one of the small molecules to study its effect on the homology-directed repair (HDR) editing efficiency in human-induced pluripotent stem cells (iPSCs) and T cells

Biochem/physiol Actions

Cyclosporin H is a selective inhibitor of formyl peptide receptor-1 (FPR-1) and formyl peptide-induced superoxide formation in neutrophils. Cyclosporin H does not bind cyclophilin or evoke an immunosuppressant response. Cyclosporin H has been reported to inhibit tumor promoting phorbol ester TPA/PMA in mouse skin cells and to inhibit calcium/calmodulin-dependent EF-2 phosphorylation.

Treatment options for patients with relapsed/refractory acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) are scarce. Recurring mutations, such as mutations in isocitrate dehydrogenase-1 and -2 (IDH1/2) are found in subsets of AML and MDS, are therapeutically targeted by mutant

Investigations of CRISPR gene knockout editing profiles have contributed to enhanced precision of editing outcomes. However, for homology-directed repair (HDR) in particular, the editing dynamics and patterns in clinically relevant cells, such as human iPSCs and primary T cells, are

Secondary infections typically worsen outcomes of patients recovering from septic shock. Neutrophil [polymorphonuclear leukocytes (PMNs)] migration to secondarily inoculated sites may play a key role in inhibiting progression from local bacterial inoculation to secondary infection.

Mutations of the mitochondrial protein paraplegin cause hereditary spastic paraplegia type 7 (SPG7), a so-far untreatable degenerative disease of the upper motoneuron with still undefined pathomechanism. The intermittent mitochondrial permeability transition pore (mPTP) opening, called flickering, is an essential process
