Antigen-specific decidual CD8+ T cells include distinct effector memory and tissue-resident memory cells

open access: yesJCI Insight, 2023
Maternal decidual CD8+ T cells must integrate the antithetical demands of providing immunity to infection while maintaining immune tolerance for fetal and placental antigens.

Common gamma chain cytokines promote rapid in vitro expansion of allo-specific human CD8+ suppressor T cells. [PDF]

open access: yesPLoS ONE, 2011
Human CD8(+) regulatory T cells, particularly the CD8(+)CD28(-) T suppressor cells, have emerged as an important modulator of alloimmunity. Understanding the conditions under which these cells are induced and/or expanded would greatly facilitate their ...

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Programmable DNA‐Peptide Hybrid Nanostructures for Potent Neutralization of Multiple Influenza a Virus Subtypes

open access: yesAdvanced Functional Materials, EarlyView.
A multivalent antiviral platform based on honeycomb‐shaped DNA nanostructures (HC–Urumin) is developed to enhance the potency and breadth of the host defense peptide Urumin. Through spatially patterned trimeric presentation, HC–Urumin disrupts influenza A virus entry, improves cell viability, and reduces disease severity in vivo‐offering a modular and ...

Protective immunity against Trypanosoma cruzi [PDF]

open access: yes, 2009
Upon infection, Trypanosoma cruzi triggers a strong immune response that has both protective and pathological consequences. In this work, several important questions regarding protective immunity are reviewed.

Bimetallic Nanoreactor Activates cGAS‐STING Pathway via mtDNA Release for Cancer Metalloimmunotherapy

open access: yesAdvanced Functional Materials, EarlyView.
A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Increased CD8+ T cell response to Epstein-Barr virus lytic antigens in the active phase of multiple sclerosis.

open access: yesPLoS Pathogens, 2013
It has long been known that multiple sclerosis (MS) is associated with an increased Epstein-Barr virus (EBV) seroprevalence and high immune reactivity to EBV and that infectious mononucleosis increases MS risk.

Positive selection of V beta 8+ CD4-8- thymocytes by class I molecules expressed by hematopoietic cells. [PDF]

open access: yes, 1993
A small subset of T cells of mature phenotype express the alpha/beta T cell receptor, but not CD4 and CD8 coreceptors (alpha/beta double-negative [DN] cells).

IL‐2 Free Expansion of T Cells with Immunofilaments

open access: yesAdvanced Healthcare Materials, EarlyView.
Ratio and density of stimulatory αCD3 and αCD28 mAb on immunofilaments (IF) influence T cell expansion, cytokine production, and effector phenotype. Moreover, IL‐2 supplementation is not necessary with optimal performing IFs, which leads to simpler culture conditions, and negative side effects of IL‐2 supplementation are reduced.
