R.I.P. Christina Takanishi

January 29, 2012 8 comments

Recently we learned that a former BMCDB student (originally enrolled in CDB before the merger from the Wood lab) Christina Takanishi has died last Wednesday (2012-01-25).

from her Google+ account

Goodbye, Chris. You will be missed.

PS:
From her former lab as can be read in the comments:
“A memorial service for Christina in Sacramento is in the works and I will pass along that information to the BMCDB GG when I receive it.
– Matt Wood”

Wish we had a graduate student community center here at UCD? Here’s your chance to be heard!

Winter Dialogue with Dean Gibeling

“Envisioning a Graduate Student Community Center”

Wednesday February 1st

Noon-2:00pm

Lunch will be provided

 

Student Community Center (across from Silo) – Meeting Room D

Moderators note: Unfortunately I will be unable to attend this day because of a wine sensory work shop, however we desperately need members of the BMCDB graduate group to go and talk to Dean Gibeling about creating a common space exclusive to graduate and professional students here at UCD. It is absurd that we have 5000+ graduate students and hardly any specific services for us on campus. It is time for us to stand up and demand facilities that will serve our graduate community for the future. You can make a real change and get a chance to discuss things with the actual dean of graduate studies – plus you get free lunch! Let me know if you are interesting in going, I can update you on the plans I have already drawn up for the community center. Thanks!

Cancer vaccine trials underway

January 25, 2012 1 comment

From the Roswell Park Cancer Institute

Dendritic cell vaccine, manufactured in unique RPCI facility, trains body’s defenses to remember, destroy cancer cell.

The Center for Immunotherapy at Roswell Park Cancer Institute (RPCI) has launched a phase I clinical research study of a dendritic cell vaccine designed to both eradicate cancer cells and prevent disease relapse. Developed at RPCI, the NY-ESO-1 dendritic cell vaccine will be manufactured in the Institute’s new Therapeutic Cell Production Facility using a unique FDA-approved process — making RPCI the first research facility in the U.S. to use a custom-made barrier isolator for vaccine cell production, and the first in the world to use this system in an approved, government-regulated study.

Dendritic cells are the gatekeepers of the human immune system, defending against invaders like bacteria, viruses and cancer. The vaccine to be produced at RPCI will be the first to incorporate a particular form of NY-ESO-1, antiDEC205-NY-ESO-1. “Armed with this specialized protein, the treated cells are then given back to the patient as a vaccine designed to recruit an army of killer immune cells that seek out and destroy cancer,” explains Kunle Odunsi, MD, PhD, Director of RPCI’s Center for Immunotherapy (CFI) and the study’s Principal Investigator.

The new study is also unique in that it’s the first to test a dendritic vaccine given in combination with rapamycin, a compound used to prevent rejection of solid-organ transplant. The study just launched will capitalize on a striking recent scientific discovery by Protul Shrikant, PhD, of the Department of Immunology at RPCI, who found that in low doses, rapamycin confers a previously unknown benefit — it prevents the immune system from using up its cancer-killing T-cells in one quick burst. “We have shown for the first time that rapamycin has the capacity to produce immune cells that have memory attributes,” explains Dr. Odunsi, who is also Chair of RPCI’s Department of Gynecologic Oncology. “The immune cells are trained to live longer and to always remember that cancer cells are bad and should be attacked and killed.”

The ability to stretch out the attack for a long-term, durable response suggests that the vaccine may be effective in preventing disease recurrence. The new NY-ESO-1 dendritic cell vaccine is expected to show great promise in patients with bladder, brain, breast, esophageal, gastrointestinal, hepatocellular, kidney, lung, melanoma, ovarian, prostate, sarcoma and uterine tumors.

The NY-ESO-1 vaccine, tailor-made for each patient, will be produced in RPCI’s Therapeutic Cell Production Facility (TCPF) under the direction of Yeong “Christopher” Choi, PhD, who notes: “We believe that our facility’s custom-made barrier isolator, the unit in which the vaccines are manufactured, is the first of its kind.” The barrier isolator — an Xvivo System processing chamber designed to RPCI’s specifications by BioSpherix, Ltd., Lacona, NY — maintains strict control of the unit’s temperature and atmospheric gases, critical for optimal production of dendritic cell vaccines.

“Those conditions, and the sterile vaccine-manufacturing environment, are rigidly maintained throughout the entire process,” says Dr. Choi. “The Xvivo — which at about 70 square feet is basically a clean room in a box — acts as a physical barrier that protects the cell-therapy product from outside contaminants, resulting in a safer, more predictable manufacturing process.”

Self assembling cell-membrane created at UCSD

January 25, 2012 Leave a comment

A recent press release from UC San Diego by Susan Brown:


Neal Devaraj watches as undergraduate student Weilong Li works on a next step in their quest to create an entirely artificial cell.

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.

Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society.

“One of our long term, very ambitious goals is to try to make an artificial cell, a synthetic living unit from the bottom up – to make a living organism from non-living molecules that have never been through or touched a living organism,” Devaraj said. “Presumably this occurred at some point in the past. Otherwise life wouldn’t exist.”

By assembling an essential component of earthly life with no biological precursors, they hope to illuminate life’s origins.

“We don’t understand this really fundamental step in our existence, which is how non-living matter went to living matter,” Devaraj said. “So this is a really ripe area to try to understand what knowledge we lack about how that transition might have occurred. That could teach us a lot – even the basic chemical, biological principles that are necessary for life.”

Molecules that make up cell membranes have heads that mix easily with water and tails that repel it. In water, they form a double layer with heads out and tails in, a barrier that sequesters the contents of the cell.

Devaraj and Budin created similar molecules with a novel reaction that joins two chains of lipids. Nature uses complex enzymes that are themselves embedded in membranes to accomplish this, making it hard to understand how the very first membranes came to be.

“In our system, we use a sort of primitive catalyst, a very simple metal ion,” Devaraj said. “The reaction itself is completely artificial. There’s no biological equivalent of this chemical reaction. This is how you could have a de novo formation of membranes.”

Staying Productive

January 24, 2012 Leave a comment

The best way to maintain a good work/life balance is to be as productive as possible during work time, but distracting websites can often get in the way. No longer.

Several plugins for your favorite web browser allow you to set time limits for the time you spend on time-wasting websites. When time is up for the day, you can’t visit those websites anymore. Once such plugin is StayFocused for Google Chrome, but similar programs exist for other browsers.
