Maternal Broadly Neutralizing Antibodies Can Select for Neutralization-Resistant, Infant-Transmitted/Founder HIV Variants

Each year, >180,000 infants become infected via mother-to-child transmission (MTCT) of HIV despite the availability of effective maternal antiretroviral treatments, underlining the need for a maternal HIV vaccine. We characterized 224 maternal HIV envelope (Env)-specific IgG monoclonal antibodies (MAbs) from seven nontransmitting and transmitting HIV-infected U.S. and Malawian mothers and examined their neutralization activities against nontransmitted autologous circulating viruses and infant-transmitted founder (infant-T/F) viruses. Only a small subset of maternal viruses, 3 of 72 (4%), were weakly neutralized by maternal linear V3 epitope-specific IgG MAbs, whereas 6 out of 6 (100%) infant-T/F viruses were neutralization resistant to these V3-specific IgG MAbs. We also show that maternal-plasma broadly neutralizing antibody (bNAb) responses targeting the V3 glycan supersite in a transmitting woman may have selected for an N332 V3 glycan neutralization-resistant infant-T/F virus. These data have important implications for bNAb-eliciting vaccines and passively administered bNAbs in the setting of MTCT.

New Padded Harness for Self-Acquisition of Resting 12-Lead ECGs

We have developed a dry-electrode harness that permits easy, rapid, and unsupervised self-acquisition of resting 12-lead ECGs without the use of any disposables. Various other advantageous features of the harness include: 1) padded or inflatable cushions at the lateral sides of the torso that function to press the left arm (LA) and right arm (RA) dry electrodes mounted on cushions against sideward (as shown in the Figure below) or downward-rested arms of the subject; 2) sufficient distal placement of the arm electrodes with good abutment and without the need for adhesives, straps, bands, bracelets, or gloves on the arms; 3) padding over the sternum to avoid "tenting" in the V1 through V3 (and V3R, when present) electrode positions; 4) easy-to-don, one-piece design with an adjustable single point of connection and an adjustable shoulder strap; and 5) Lund or "modified Lund" placement of the dry electrodes, the results of which more effectively reproduce results from "standard" 12-lead ECG placements than do results from Mason-Likar lead placements.

In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to four O2- and three F1- atoms. There are two shorter (2.43 Å) and two longer (2.68 Å) Na–O bond lengths. There are two shorter (2.48 Å) and one longer (2.61 Å) Na–F bond lengths. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- and three F1- atoms. There are two shorter (2.42 Å) and two longer (2.95 Å) Na–O bond lengths. There are two shorter (2.42 Å) and one longer (2.75 Å) Na–F bond lengths. In the third Na1+ site, Na1+ is bonded in a 7-coordinate geometry to four O2- and three F1- atoms. There are two shorter (2.44 Å) and two longer (2.51 Å) Na–O bond lengths. There are one shorter (2.47 Å) and two longer (2.48 Å) Na–F bond lengths. V3+ is bonded to four O2- and two F1- atoms to form VO4F2 octahedra that share a cornercorner with one VO4F2 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 2°. There are a spread of V–O bond distances ranging from 1.99–2.07 Å. Both V–F bond lengths are 2.02 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 43–45°. All P–O bond lengths are 1.55 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 43–44°. There is two shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Na1+, one V3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+, one V3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one V3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one V3+, and one P5+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to three Na1+ and one V3+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to three Na1+ and two equivalent V3+ atoms.
