Invasive salmonellosis caused by Salmonella enterica serovar Typhimurium ST313 is a major health crisis in sub-Saharan Africa, with multidrug resistance and atypical clinical presentation challenging current treatment regimens and resulting in high mortality. Moreover, the increased risk of spreading ST313 pathovars worldwide is of major concern, given global public transportation networks and increased populations of immunocompromised individuals (as a result of HIV infection, drug use, cancer therapy, aging, etc). While it is unclear as to how Salmonella ST313 strains cause invasive disease in humans, it is intriguing that the genomic profile of some of these pathovars indicates key differences between …

Viral protein U (Vpu) is a type-III integral membrane protein encoded by the Human Immunodeficiency Virus-1 (HIV- 1). It is expressed in infected host cells and plays vital roles in down-regulation of CD4 receptors in T cells and also in the budding of virions. But, there remain key structure/function questions regarding the mechanisms by which the Vpu protein contributes to HIV-1 pathogenesis and thus, it makes for an attractive target to study the structural attributes of this protein by elucidating a structural model with X-ray crystallography. This study describes a multi-pronged approach of heterologous over-expression of Vpu. The strategies of …
