But rather than delivering the entire gene for the clotting - factor proteins to cells, as most gene therapies do, the researchers used the viruses to engineer immune - regulating B cells to express a fragment of the clotting factor fused to an immune molecule called an immunoglobulin.

Now a team of engineers at MIT has developed a new way to deliver such vaccines directly to the lymph nodes, where huge populations of immune cells reside: These vaccines hitch a ride to the lymph nodes by latching on to the protein albumin, found in the bloodstream.

Using a combination of human or specially engineered mouse cells in vitro and in vivo animal models, study senior investigator Judy Lieberman, MD, PhD; study lead investigator Farokh Dotiwala, PhD, with a team lead by the Brazilian parasitologist Ricardo Gazzinelli, DSc, DVM, found that when an immune killer cell, such as a T - cell or natural killer (NK) cell, encounters a cell infected with any of three intracellular parasites (Trypanosoma cruzi, Toxoplasma gondii or Leishmania major), it releases three proteins that together kill both the parasite and the infected cell:

And, in fact, these doctors and researchers are finding incredible success with this strategy; for example, PD - 1 inhibitors remove this «cloak» that cancers use to hide from the immune system, and CAR - T cell therapies use specially engineered T - cells to seek cancer - specific proteins and destroy the cancer cells to which they are attached.

Two types of vaccines were used for the study: one constructed with genetically engineered DNA molecules that teach immune system cells to recognize premalignant cells expressing HPV16 E7 proteins, and one that is a non-infectious, engineered virus that targets and kills precancerous cells marked by HPV16 and HPV18 E6 and E7 proteins.

The technique could make drug - producing bacteria immune to viruses, prevent laboratory engineered organisms from genetically contaminating wildlife and enable scientists to construct proteins that do not exist in nature.

By engineering red blood cells to have «sticky» proteins on their surface, a team of researchers has given the cells the ability to carry anything from drugs to treat immune disorders or cancer to radioactive molecules used in imaging of blood vessels.

A central question has been answered regarding a protein that plays an essential role in the bacterial immune system and is fast becoming a valuable tool for genetic engineering.

It contains an engineered protein that combines a protein fragment from the malaria parasite, Plasmodium falciparum, and a protein from the Hepatitis B virus that helps trigger a strong immune response.

The most advanced to date — dubbed RTS, S — tries to teach the immune system to defeat the parasite with a genetically engineered version of a protein from Plasmodium falciparum, the strain that causes the most serious disease in humans.

To get to the bottom of this question, researchers in the Perelman School of Medicine at the University of Pennsylvania engineered mice in which the damage caused by a mutant human TDP - 43 protein could be reversed by one type of brain immune cell.

It is in this final tank that the engineered cells are stimulated to secrete the protein product — the monoclonal antibody itself, a protein derived from the mammalian immune system that can bind to a very specific target in the body, such as a tumor cell.

The awards span the broad mission of the NIH and include groundbreaking research, such as engineering immune cells producing drugs at the site of diseased tissue; developing a sensor to rapidly detect antibiotic resistance of a bacterial infection; understanding how certain parasites evade host detection by continually changing their surface proteins; and developing implants that run off the electricity generated from the motion of a beating the heart.

By engineering an artificial protein that targets the product of such potentially cancer - causing gene fusions, Hur hopes to trigger immune defense mechanisms that kill rogue cells harboring the fusions.

The approach developed by the MGH team starts with the engineered protein, which in this case fuses an antibody fragment targeting a protein called mesothelin — expressed on the surface of such tumors as mesothelioma, ovarian cancer and pancreatic cancer — to a protein from the tuberculosis bacteria that stimulates the activity of dendritic and other immune cells.

To that end, she genetically engineered mice to lack a protein that transports cholesterol out of cells in order to analyze experimentally what happens when immune cells remain abnormally packed with cholesterol.

As noted above, existing cancer vaccines that use dendritic cells require extracting cells from a patient's blood, treating them with an engineered protein or nucleic acid that combines tumor antigens with immune - stimulating molecules, and returning the activated dendritic cells to the patient.

The process uses an engineering technique called reserve genetics and allows scientists to remove a protein from both flu viruses, weakening them considerably, but still promoting an immune system response in the dogs that won't make them sick.
