Uninfected and A. phagocytophilum NCH-1 strain–infected human promyelocytic HL-60 cells (CCL-240; American Type Culture Collections [ATCC]) and RF/6A rhesus monkey choroidal endothelial cells (CRL-1780; ATCC) were cultured as previously described (Huang et al, 2010a (link)). HeLa human cervical epithelial cells (CCL-2; ATCC) were maintained as described (Justis et al, 2017 (link)). C. burnetii Nine Mile Phase II (NMII; clone 4, RSA439) and mCherry-C. burnetii NMII were purified from Vero cells (African green monkey kidney epithelial cells; CCL-81; ATCC) or acidified citrate cysteine medium-2 (ACCM-2) and stored as described (Cockrell et al, 2008 (link); Beare et al, 2009 (link)). Mouse alveolar macrophages (MH-S; CRL-2019; ATCC) and THP-1 human monocytic cells (TIB-202; ATCC) were maintained as described (Mulye et al, 2018 (link)). THP-1 cells were differentiated into macrophage-like cells by overnight treatment with 200 nM phorbol 12-myrisate 13-acetate (MilliporeSigma). C. trachomatis serovar L2 (LGV 434) was maintained in HeLa cells at 37°C as described (Rucks et al, 2017 (link)). C. pneumoniae AR39 was maintained in HeLa cells at 35°C as described (Ouellette et al, 2016 (link)). Mammalian cell cultures were low passage and confirmed to be mycoplasma free using the Universal Mycoplasma Detection kit (ATCC) or Mycoplasma PCR Detection kit (MilliporeSigma).

Uninfected and A. phagocytophilum (NCH-1 strain)-infected human promyelocytic HL-60 cells [CCL-240; American Type Culture Collections (ATCC), Manassas, VA] and RF/6A rhesus monkey choroidal endothelial cells (CRL-1780; ATCC) were cultured as described previously (Huang et al., 2010b (link)). HeLa 229 epithelial cells (CCL-1.2; ATCC) were grown in Roswell Park Memorial Institute 1640 (Invitrogen, Carlsbad, CA) supplemented with 10% foetal bovine serum (FBS; Gemini Bio-Products, Sacramento, CA) at 37°C with 5% CO2. HEK-293T cells were cultured in Dulbecco’s modified Eagle’s medium with l-glutamine, 4.5 g l−1 of d-glucose and 100 mg l−1 of sodium pyruvate (Invitrogen) supplemented with 10% FBS, 1× minimal essential medium non-essential amino acids (Invitrogen) and 15 mM of HEPES (Affymetrix, Cleveland, OH) at 37°C with 5% CO2. Human neutrophils were isolated from peripheral blood from healthy donors using Polymorphprep (Axis-Shield; Greiner Bio-One, Frickenhausen, Germany) as described previously (Carlyon et al., 2004 (link)). The protocol (HM11407) for obtaining donor blood for the purpose of isolating neutrophils has been reviewed and approved by the Virginia Commonwealth University Institutional Review Board with respect to scientific content and compliance with applicable research and human subjects regulations.

RF/6A (Choroid-retinal endothelial cells; CRL-1780™, ATCC, United States) cells were cultured in Dulbecco’s Modified Eagle Medium (DMEM, Gibco BRL, United States) supplemented with 10% fetal bovine serum (FBS, ScienCell, United States) and antibiotics (100 U/ml penicillin and 100 μg/ml streptomycin; Gibco, United States). All cells were maintained at 37°C in an incubator containing 5% CO2 and 95% air.

Monkey endothelial cells of choroid-retina (CRL-1780; ATCC™, Manassas, Virginia), porcine aortic endothelial (PAE) cell lines expressing KDR (PAE/KDR) and, PDGFβ-R (PAE/β-R) (27 (link)) and human retinal pigment epithelial cells (ARPE-19, American Type Culture Collection) were cultured in Ham's F-12/DMEM medium supplemented with 10% fetal calf serum (FCS) (Cambrex, East Rutherford, NJ). The following antibodies were used in this study; monoclonal anti TIMP3 antibody from Chemicon International, Inc (Temecula, CA), anti-phosphotyrosine mAb, clone 4G10 and anti-paxillin mAb, clone 5H11 from Upstate Biotechnology Inc (Lake Placid, NY), anti-FAK mAb, clone 77 from Transduction Laboratories (Lexington, KY), anti-Bax (P-19), anti-Bcl2 rabbit polyclonal antibodies and anti-actin (C-11) goat polyclonal antibody from Santa Cruz Biotechnology (Dallas, TX). Growth factor reduced matrigel was purchased from BD Biosciences (Bedford, MA). Z-VAD-FMK (pan-caspase inhibitor), Z-DEVD-FMK(caspase-3 inhibitor II) and Z-IETD-FMK(caspase inhibitor II) were purchased from Calbiochem (Darmstadt, Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
