Cell division speeds up as part of antibody selection, study shows

Cell division speeds up as part of antibody selection, study showsIn response to an infection, the immune system refines its defensive proteins, called antibodies, to better target the invader. New research has revealed two mechanisms that favor the selection of B cells capable of producing antibodies finely tuned to target that invader. More »

Sequential immunizations could be the key to HIV vaccine

Sequential immunizations could be the key to HIV vaccineScientists have thought for some time that multiple immunizations, each tailored to specific stages of the immune response, could be used to generate a special class of HIV-fighting antibodies, so-called broadly neutralizing antibodies. These findings provide the first evidence supporting this approach. More »

Key to blocking influenza virus may lie in a cell’s own machinery

Key to blocking influenza virus may lie in a cell’s own machineryResearchers have found that the immune system fights a flu infection by turning off cellular enzymes the virus needs to put the final touches on new viral particles. The unfinished particles cannot spread infection to new cells. More »

Discovery helps explain how B cells adapt to their targets

Gitlin-b-cells-thumb2-05052014During an infection, the immune system selects B cells that produce antibodies with a high affinity for the pathogen. New research helps explain the details of how these cells are selected and amplified. More »
