A decades-long scientific challenge in HIV vaccine development has been finding a way to train the immune system to produce antibodies that can target many variants of the virus. Traditional approaches haven't worked -- largely because HIV mutates rapidly and hides key parts of itself from the immune system.
Immunotherapies, which mobilize the body's immune defenses against a cancer, have not been effective for GBM, in part because the tumor's surrounding environment is largely impenetrable to assaults from the body's immune system.

HLA-II presents peptides to CD4 T cells thought to be important for indirectly helping immuneresponses and facilitating antibody production.
Even as several safe and effective COVID-19 vaccines are being administered to people worldwide, scientists are still hard at work developing different vaccine strategies that could provide even stronger or longer-lasting immunity against SARS-CoV-2 and its variants.
UK firm develops solution for identifying whether patients are actually infectious from a virus or not. Iceni Diagnostics has revealed it is developing a new technology that can disclose if patients are actually infectious with a live virus or not.
These data reinforce the potential function of a third dose of the vaccine in maintaining high levels of protection against the virus in this age group. The neutralizing GMT against the wild-type virus was 2153 (after three doses), compared to 335 after two doses. About Pfizer: Breakthroughs That Change Patients’ Lives.

Strong Th1 cell-mediated immuneresponses were also observed for the vaccine candidates with either adjuvant. We are encouraged by the high level of neutralizing antibodies in combination with the strong Th1 response which we believe could play an important role in controlling infection.
Science, 2020 One way to fight COVID-19 is with drugs that directly target SARS-CoV-2, the novel coronavirus that causes the disease. Another promising strategy is drugs that target the proteins within human cells that the virus needs to infect, multiply, and spread. Credit: DE Gordon et al.,
If a virus is disease-causing, the right mutation can allow the virus to escape the immuneresponse by changing the viral pieces the immune system uses to recognize the virus as a threat, pieces scientists call epitopes.
Adjuvanted S-Trimer COVID-19 vaccine candidates demonstrated favorable safety and tolerability profiles and strong neutralizing immuneresponses in a phase 1 trial.

“We continue to see the strongest effects in patients who are most at risk for poor outcomes due to high viral load, ineffective antibody immuneresponse at baseline, or pre-existing risk factors. In the overall patient group with detectable virus at baseline, the average daily reduction in viral load through day 7 was a 0.36
11, 2020 — More than 15 million Americans have been infected by the COVID-19 virus, and many may be questioning whether they need to receive one of the two coronavirus vaccines now on the verge of approval from U.S. It’s one reason why science has yet to come up with a cure for the common cold. FRIDAY, Dec. regulators.
Blocking an immuneresponse-related enzyme holds promise in preventing or treating severe COVID-19 symptoms by reducing inflammation, tissue injury and blood clots in the lungs, new research in mice suggests. The research was published online recently in Proceedings of the National Academy of Sciences.

GSK’s response to COVID-19 has been one of the broadest in the industry, with two potential treatments in addition to our vaccine candidates in development. GSK commitment to tackling COVID-19.
The study’s outcomes are also the fruit of a fruitful collaboration involving scientists from the RIKEN Center for Integrative Medical Sciences in Japan, alongside local research teams from UC San Diego and the Salk Institute. This led her lab to conduct a more thorough examination of retinoic acid receptors, including RARα.
Challenges of viral capsids in gene therapy efficiency A widely used production method of rAAV vectors requires co-transfection of host cell lines with three plasmids, including one carrying the transgene of interest, one carrying the capsid and replication sequences, and a helper virus to circumvent the inability of rAAV to self-amplify.
The public health relevance of the refrigerator temperature-stable adjuvanted protein-based Sanofi-GSK vaccine is strongly supported by the induction of robust immuneresponses and a favorable safety profile in multiple settings. The Sanofi-GSK vaccine demonstrates a universal ability to boost all platforms and across all ages.
Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis. This is how many medical studies begin, said biomedical engineering professor Phil Bourne, who serves as founding dean for the School of Data Science.
. “To our knowledge, this study is the first to show in vivo [in a living organism] protection against severe COVID-19 by an AI-designed T-cell vaccine,” said Girish Kirimanjeswara, associate professor of veterinary and biomedical sciences, Penn State. “RAVEN is really adaptable,” Sørensen said.

The immune system can carry out many biological processes, from killing viruses to fighting cancer, thanks in large part to approximately 100 key cell-signaling proteins called cytokines, which instruct immune cells what to do. For many immune-mediated diseases, there's no cure or treatment. Did any results surprise you?
The core of the CRISPR immuneresponse is a guide RNA (gRNA) that binds to a CRISPR-associated (Cas) protein. If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein.
