“Endothelial Cell Inflammatory Reactions Are Altered in the Presence of E-Cigarette Extracts of Variable Nicotine” Barber, K.E., Ghebrehiwet, B., Yin, W. et al. (2017) Cel. Mol. Bioeng. 10: 124. doi:10.1007/s12195-016-0465-4   The Authors utilized an in vitro model in which HUVEC (human umbilical cord endothelial cells) were exposed to tobacco vapor/ in HEPES buffer to […]

An Ohio research group tested the efficacy of inactivated Swine Influenza virus (SwlV) encapsulated in 200–300 nm diameter PLGA (poly lactic co-glycolic acid) microspheres. Pigs were immunized twice intranasaly.  While control pigs had fever for four days, treated pigs showed no clinical flu symptoms.  “Biodegradable nanoparticle delivery of inactivated swine influenza virus vaccine provides heterologous

CD36 is a scavenger receptor which can bind to various ligands as well as long chain fatty acids.  It plays a role in innate immunity as well as metabolism.  The authors use transport inhibitors, and uptake of 14-C labeled Phosphate diester of alpha-Tocopheryl (Vitamin E ) to implicate the CD36/PI3Ky as an important pathway for

Macrophages derived in culture from SLE patients are directed into secreting proinflammatory cytokines by anti-C1q auto antibodies bound to immobilized C1q complement protein. Pre blocking these monocytes with anti-CD32 (FcgRII ) F(ab’)2 reduced cytokine secretion levels significantly. “Anti-C1q Autoantibodies from Systemic Lupus Erythematosus Patients Induce a Proinflammatory Phenotype in Macrophages.”  Sophia Thanei, Marten Trendelenburg  J

Using TALEN(Transcription Activator-Like Effector Nucleases) technology, these researchers from Seattle Children’s Research succeeded in restoring copies of CD154( CD40L) gene with 3’ UTR under control of its endogenous promoter in human T cells from a patient with X-Linked Hyper-IgM Syndrome (X-HIGM). “Targeted gene editing restores regulated CD40L expression and function in X-HIGM T cells.” N
