Cias Zembe1, Eitel Mpoudi-Ngole2, Carolyn Williamson1,4 and Wendy A Burgers1*AbstractBackground: Cameroon, in west central Africa, has an extraordinary degree of HIV diversity, presenting a major challenge for the development of an effective HIV vaccine. Given the continuing need to closely monitor the emergence of new HIV variants in the country, we analyzed HIV-1 genetic diversity in 59 plasma s

We sequenced 50 full length HIV-1 gag and 55 nef genes from 59 HIV-infected blood donors in Cameroon. To obtain a phylogenetic view of Cameroonian HIV diversity that explicitly accounted for the confounding effects of recombination, we pe

Pacity of latex beads similar to primary AMs deficient in MARCO and SR-AI/II. All three clones showed significantly decreased uptake of fluorescent latex beads compared to the wild type primary AMs (Fig. 6A). Observed differences in phagocytic capacity between these clones and parental primary AMs from MS-/- mice may reflect the heterogeneity seen in populations of primary alveolar macrophages.ZK1

Bited a 325-bp PCR product, whereas SR-AI/II-/- mutant allele showed a 434-bp PCR product. MARCO wild type allele exhibited ca. 500-bp PCR product, and MARCO-/- mutant exhibited ca. 850-bp PCR product. All of the three cell lines are stable and Mycoplasma-free by Mycoplasma PCR ELISA test (Roche, Indianapolis, IN) during culture in the past 24 months.SR-AI/IIM WT ZK1 ZK2 ZK6 MMARCOWT ZK1 ZK2 ZKMAR

Black squares at the end of the branches represent the gag and nef sequences sampled from Cameroon in this study, while red squares represent intragene recombinant fragments in our samples. The gag tree was rooted using HIV-1 group N, O, P and SIV CPZ isolates, while t
