Microbubble Macrophages Track Tumors #ASA184

At the 184th ASA Meeting, Ashley Alva of the Georgia Institute of Technology will describe how attaching microbubbles to macrophages, a type of white blood cell, can create high-resolution and sensitive tracking images useful for disease diagnosis. Because of the attached microbubbles, the cells sent back an echo when hit with ultrasound, which is nonionizing and noninvasive and has great depth of penetration. This allowed the team to visualize the macrophages in vivo with high resolution and sensitivity. Visualizing macrophages in vivo could also provide a powerful tool for understanding immune responses and monitoring therapeutic efficacy.

Cedars-Sinai Investigators ID Gene Critical to Human Immune Response

Cedars-Sinai investigators have identified a gene that plays an essential role in the innate human immune system. The gene, NLRP11, helps activate the inflammatory response that tells the body’s white blood cells to go on the attack against a foreign presence.

‘Fortunate Accident’ May Yield Immunity Weapon Against Antibiotic-Resistant Bacteria

In what turned out to be one of the most important accidents of all time, Scottish bacteriologist Alexander Fleming returned to his laboratory after a vacation in 1928 to find a clear zone surrounding a piece of mold that had infiltrated a petri dish full of Staphylococcus aureus (S. aureus), a common skin bacterium he was growing.

Trojan horses and tunneling nanotubes: Ebola virus research at Texas Biomed gets NIH funding boost

Scientists have a general idea of how viruses invade and spread in the body, but the precise mechanisms are actually not well understood, especially when it comes to Ebola virus. Olena Shtanko, Ph.D., a Staff Scientist at the Texas Biomedical Research Institute (Texas Biomed), has received more than $1 million from the National Institutes of Health (NIH) to explore different aspects of Ebola virus infection.

Study Explores Regulatory Role for White Blood Cells in Recruitment of Brown Fat

Article title: Thermogenic recruitment of brown and brite/beige adipose tissues is not obligatorily associated with macrophage accretion or attrition Authors: Nathalie Boulet, Ineke H.N. Luijten, Barbara Cannon, Jan Nedergaard From the authors: “A regulatory or mediatory role—positive or negative—for macrophages…

Protein that Keeps Immune System from Freaking Out Could Form Basis for New Therapeutics

Treatment with a peptide that mimics the naturally occurring protein GIV prevents immune overreaction and supports a mechanism critical for survival in mouse models of sepsis and colitis, according to a UC San Diego study.

Researchers Identify a Protein That Is Critical for Wound Healing after a Central Nervous System Injury

after a Central Nervous System Injury

(New York – March 2, 2020) Plexin-B2, an axon guidance protein in the central nervous system (CNS), plays an important role in wound healing and neural repair following spinal cord injury (SCI), according to research conducted at the Icahn School of Medicine at Mount Sinai and published today in Nature Neuroscience.
