Washington: Scientists have for the first time built a detailed molecular model of the complex structure of the inner protein shell of HIV, paving way for potential new treatments for the deadly virus.
A team led by researchers at the University of Pittsburgh School of Medicine described the 4-million-atom structure of the HIV's capsid, or protein shell. The findings, published in the journal Nature, could lead to new ways of fending off an often-changing virus that has been very hard to conquer.
Scientists have long struggled to decipher how the HIV capsid shell is chemically put together, said senior author Peijun Zhang, associate professor at the University of Pittsburgh School of Medicine.
"The capsid is critically important for HIV replication, so knowing its structure in detail could lead us to new drugs that can treat or prevent the infection," she said....
