CD8+ T cell memory is sustained in mice by hepatic stellate cells

open access: yesHepatology, EarlyView., 2022
HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.

Tuning Mechanoreceptor Signaling Enhances the Adjuvant Effect of Biomaterial Vaccines

open access: yesAdvanced Functional Materials, EarlyView.
Matrix stiffness serves as an independent immunological signal in biomaterial vaccines. Stiffer microporous hydrogel vaccines enhance dendritic cell maturation and migration to draining lymph nodes, promote T follicular helper cell expansion through Yap/Taz signaling, and increase antigen‐specific antibody production.

Nanomaterial Strategies for Pulmonary Delivery of Immunotherapeutics in Lung Cancer Treatment

open access: yesAdvanced Healthcare Materials, EarlyView.
Inhalable immunotherapeutic nanomedicines enable organ‐selective immune modulation by overcoming pulmonary delivery barriers and concentrating therapy within lung tumors. This Review defines how nanomaterial properties govern airway deposition, retention, cellular partitioning, and immune activation across vaccines, checkpoint blockade, STING agonists,

Investigation of the Effect of Polycystic Ovary Syndrome on the Expression of the Sirtuin-3 Gene in the Ovum of the NMRI Mice

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Īlām, 2022
Introduction: Increasing levels of free radicals in the ova reduce the quality of their fertilization. Investigations have revealed the elevated production of tissue and serum-free radicals in women with polycystic ovary syndrome. Sirtuin-3 is located in

Ionizable Lipid‐Dependent Optimization of Steroid Lipid Nanoparticles With Tunable Immunomodulatory Properties

open access: yesAdvanced Materials, EarlyView.
A novel engineering strategy that establishes material design principles for incorporating anti‐inflammatory steroids into lipid nanoparticles to reduce LNP‐induced inflammation while retaining mRNA delivery. Results are validated in vitro and in three animal models of inflammation and autoimmunity in vivo.

Ovum Transport in the Ewe [PDF]

open access: yesAustralian Journal of Biological Sciences, 1972
Ovum transport was examined using 60 mature Border Leicester X Merino ewes, the time of ovulation being determined by endoscopy. By 6 hr after ovulation, all ova had reached the middle segment of the ampulla and some had reached the ampulla-isthmus junction (AIJ). At 8 hr, most ova were located at the AIJ.

Anisotropic Masked Mycobacterium Potentiates Amplified Antitumor Trained Immunity via Spleen Targeting and Myelopoiesis Conversion

open access: yesAdvanced Materials, EarlyView.
An engineered Trojan Mycobacterium, developed via a “peeling‐off and masking‐up” strategy, functions as a powerful splenic myelopoiesis converter. This spleen‐targeted nanomedicine induces trained immunity to reprogram immunosuppressive myeloid reservoirs into antitumoral effectors.
