and where antibodies against Anapn1 that can and can't block parasite development, bind to the protein.
Vaccinated individuals in malaria-endemic countries produce antibodies to Anapn1. During routine disease transmission, when these same immunised individuals become infected with malaria parasites,
both antibodies and parasites are ingested by a mosquito during blood feeding. The antibodies block parasite development in the mosquito
breaking the cycle of transmission. The Anapn1 protein is a leading candidate for a mosquito-based malaria transmission-blocking vaccine that is being developed by Dr Dinglasan."
"This type of vaccine won't boost people's immunity to malaria, but instead it will provide a delayed benefit to the individual by protecting the entire community from parasite transmission,
Dr Dinglasan said as a vaccine antigen, Anapn1 prompts people to make antibodies; however only some of these antibodies block parasite transmission,
while others do not.""This dilution of the overall antibody response to Anapn1 is problematic.
To further improve vaccine immunogenicity at the preclinical stage, we need to immuno-focus the antibody response to only the critical,
'transmission-blocking'regions of the protein, "he said. An understanding of how Anapn1 antibodies that are generated can block parasite transmission to mosquitoes
and their binding region on Anapn1 has remained elusive until now. Using the Australian Synchrotron, Dr Borg's team at Monash University were able to visualise the crystal structure of the Anapn1 protein for the first time, providing valuable insights.
Dr Dinglasan's team then provided the critical functional data to support the hypotheses generated by the Anapn1 structure."
In combination with other experimental data, the structure enabled us to pinpoint the binding site of Anapn1 antibodies that can
"We now know much more about which parts of the Anapn1 protein are involved in generating transmission-blocking antibodies
This discovery will fuel further work to understand what critical interaction the Anapn1 transmission-blocking antibodies are blocking.
It will also prompt the redesign of the Anapn1 antigen to make it more effective e

In most parts of the body, antigens molecules on pathogens or foreign tissue that alert our immune system to potential threats are presented to white blood cells in our the lymph nodes causing an immune response.
and hence were curious about the role of meningeal immunity on brain function. By mounting whole mouse meninges and using neuroimaging the team noticed that T-cells were present in vessels separate from arteries and veins
Perhaps antigens from the infectious culprit find their way to the cervical lymph nodes via the meningeal lymphatic vessels,
For example, pharmaceutical companies currently create cancer antibodies in expensive hamster ovary cells that do not often misfold proteins.
and display pieces of viral or bacterial proteins (known as antigens) on their cell surfaces. When these B cells encounter T cells with receptors that recognize the antigen the T cells become activated provoking them to release cytokines inflammatory chemicals that control the immune response
or to seek out and destroy infected cells. Although all of the T cells in this study had identical T cell receptors the MIT team found that they did not all respond the same way after encountering B cells carrying identical antigens on their surfaces.
Using calcium imaging to measure T cell activation the researchers found that the initial activation level depends on how much of the antigen is presented.
At high levels most of the cells respond the same way. However at lower antigen levels the T cell responses vary greatly.
These differences also correlated to differences in T cell cytokine production. In future studies the researchers hope to further trace how T cells go through the decision-making process that determines their eventual fates.

The team found antibodies (as above) that identify and neutralize Marburg virushich inflicts a mortality rate of up to 90 percent. hese antibodies attack a new site on Marburg virus we had seen not before,

shows that mixtures or ocktailsof antibodies can block Ebola virus from infecting new cells and alert the immune system to the presence of the infection.
Antibodies against one site on Marburg were revealed in a study by Vanderbilt University and TSRI in February 2015,
but complementary antibodies needed against other sites remained to be discovered. In the new study, TSRI researchers designed proteins which elicited new antibodies developed at Emergent biosolutions.
Other antibodies in the study were identified independently at Mapp Biopharmaceutical and Integrated Biotherapeutics which collaborated with TSRI for molecular analysis. Some of the new antibodies target a new site on Marburg virus not seen before winglike feature attached to the base of the virus. Antibodies against this newly discovered site protected 90 to 100%of infected animal models from lethal infection.
Ebola virus Also Vulnerablesome antibodies discovered in the new study are also able to cross-react with Ebola virus
and its four relatives in the Ebolavirus genus. e expect both Marburg virus and Ebola virus to emerge again
and to acquire new mutations, said TSRI Research Assistant Marnie Fusco, first author of the new study. he cross-reactive antibodies could be used as diagnostics for newly emerging strains.?
The high cost of creating independent vaccines or treatments for each of the different viruses in this family necessitates intelligent design of immunogens (antibody-inducing molecules).
The molecular images used to design the molecules and evaluate the antibodies point the way forward, added Jody Berry, the former Director of Pipeline Research of Emergent biosolutions,
who initiated the study with Saphire six years ago. nderstanding where and how the antibodies interact with the virus tells us which regions can be targeted
