Rapid and Efficient Affinity Isolation of Engineered Extracellular Vesicles Encapsulating Functional Proteins via Internal Twin‐Strep Tetraspanin Tagging

Small, EarlyView.
Structure‐guided internal twin‐Strep tagging of the tetraspanins CD63 or CD9 enables rapid and efficient antibody‐free affinity isolation of engineered extracellular vesicles (EVs) using Strep technology while allowing luminal protein loading. The approach removes over 96% of contaminants, separates tagged EVs from coexisting viral particles, and ...

Ancient, independent evolution and distinct molecular features of the novel human T-lymphotropic virus type 4

Retrovirology, 2009
Background Human T-lymphotropic virus type 4 (HTLV-4) is a new deltaretrovirus recently identified in a primate hunter in Cameroon. Limited sequence analysis previously showed that HTLV-4 may be distinct from HTLV-1, HTLV-2, and HTLV-3, and their simian ...

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

Trends in the prevalence and distribution of HTLV-1 and HTLV-2 infections in Spain

Virology Journal, 2012
Background Although most HTLV infections in Spain have been found in native intravenous drug users carrying HTLV-2, the large immigration flows from Latin America and Sub-Saharan Africa in recent years may have changed the prevalence and distribution of ...

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

HTLV screening and confirmatory testing among blood donors in São Paulo: A cross‐sectional study

Transfusion Medicine, EarlyView.
Abstract Introduction Human T‐cell lymphotropic virus types 1 and 2 (HTLV‐1/2) are transfusion‐transmissible retroviruses associated with severe diseases, and blood donor screening is mandatory in Brazil. Increasing HTLV‐related discard rates at our institution prompted this study to determine the prevalence and incidence of HTLV‐1/2 and to investigate

Budget impact of implementing universal Plasmodium NAT screening in the blood transfusion system in the US

Transfusion, EarlyView.
Abstract Background Blood donor deferral for malaria risk relies exclusively on responses to self‐reported questionnaires. This study evaluated the economic impact of introducing Plasmodium nucleic acid testing (NAT) as a universal screening strategy in the United States.
