ANSWER: bNAbs- Broadly Neutralising Antibodies
Explanation:
A new antibody called banks has been promoted to prevent HIV infection associated with AIDs. bNAbs has been found in blood samples of HIV patients whose immune system has naturally contained the infection. Antibodies protect the patient through recognition of protein called envelope spike present in surface of HIV strains and neutralising the impact of this virus. CalTech researchers have discovered one bNAb which may recognise the rapidly changing signature protein during the course of the HIV infection making it easier to detect and neutralise.
