The primary immune constituents in the brain, microglia and macrophages, are the target for HIV in people and simian immunodeficiency virus (SIV) in nonhuman primates. This infection can lead to neurological dysfunction, known as HIV-associated neurocognitive disorder (HAND). Given the gaps in our knowledge on how these cells respond in vivo to CNS infection, we perform single-cell multiomic sequencing, including gene expression and ATAC-seq, on myeloid cells from the brains of rhesus macaques with SIV-induced encephalitis (SIVE) as well as uninfected controls.

J Trauma Acute Care Surg

January 2025

From the Division of Acute Care Surgery, Department of Surgery (E.R.M., T.B.M., C.M.W., H.S., R.H., C.D.B.), University of Nebraska Medical Center, Omaha, Nebraska; Department of Surgery (H.B.M.), AdventHealth Porter; Department of Surgery (E.E.M., J.G.C.), Ernest E Moore Shock Trauma Center at Denver Health, Denver; Department of Surgery (E.E.M.), University of Colorado Anschutz Medical Campus, Aurora, Colorado; Hunter College (I.M.B.), New York, New York; Sauaia Statistical Solutions, LLC (A.S.), Denver, Colorado; and Department of Cellular and Integrative Physiology (F.I.G., C.D.B.), University of Nebraska Medical Center, Omaha, Nebraska.

Background: Tissue-plasminogen activator-challenged thromboelastography (tPA-TEG) predicts massive transfusion and mortality better than conventional rapid thromboelastography (rTEG), with little concordance between their lysis values (LY30). We hypothesized that the main fibrinolytic inhibitors plasminogen activator inhibitor-1 (PAI-1) and α-2 antiplasmin (A2AP), as well as markers of fibrinolytic activation (plasmin-antiplasmin [PAP], tPA-PAI-1 complex, tPA activity), would correlate more strongly with tPA-TEG versus rTEG LY30 and may explain the recent findings of four distinct fibrinolytic phenotypes in trauma based on these two TEG methodologies.

Methods: Adult trauma patients (n = 56) had tPA-TEG, rTEG, and plasma obtained on arrival to the emergency department with institutional review board approval.

Aim: Tissue clearance is a rapidly evolving technology that allows for the three-dimensional imaging of intact biological tissues. Preexisting tissue-clearing techniques, such as Passive Clarity Technique (PACT) and Clear Unobstructed Brain Imaging Cocktails and Computational Analysis (CUBIC), clear tissues adequately but have distinct disadvantages, such as taking extensive time to clear tissues and degradation of endogenous tissue fluorescence. We developed a new tissue-clearing technique combining PACT and CUBIC protocols to map the neural lineages expressing the transient receptor potential vanilloid type 1 (TRPV1) receptor.
