Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Role of CD4 epitopes outside the gp120-binding site during entry of human immunodeficiency virus type 1 [PDF]

, 1997
CD4 is the primary receptor for human immunodeficiency virus (HIV). The binding site for the surface glycoprotein of HIV type 1 (HIV-1), gp120, has been mapped to the C'-C" region of domain 1 of CD4. Previously, we have shown that a mutant of rat CD4, in

Biomimetic Hybrid‐Membrane Nanoreactor for Deep‐Seated Photodynamic Immunotherapy of Hepatocellular Carcinoma via Dual Catalysis‐Enhanced ROS Amplification and cGAS‐STING Activation

Advanced Functional Materials, EarlyView.
UCNP@MnOx‐Hyp@HRM (UMHM) enables tumor targeting and accumulation. Under 808 nm NIR irradiation, PDT/CDT synergistically triggers ICD and cGAS–STING immunity for deep hepatocellular carcinoma therapy. ABSTRACT Photodynamic therapy (PDT) is promising against hepatocellular carcinoma (HCC).

Antigen delivery to dendritic cells shapes human CD4+ and CD8+ T cell memory responses to Staphylococcus aureus. [PDF]

PLoS Pathogens, 2017
Intracellular persistence of Staphylococcus aureus favors bacterial spread and chronic infections. Here, we provide evidence for the existence of human CD4+ and CD8+ T cell memory against staphylococcal antigens.

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

Macroautophagy in endogenous processing of self and pathogen derived antigens for MHC class II presentation

Frontiers in Immunology, 2015
Although autophagy is a process that has been studied for several years its link with antigen presentation and T cell immunity has only recently emerged.

Role and specificity of regulatory T cells during retroviral infection [PDF]

, 2009
During chronic viral infection of the hematopoietic system, both virus-mediated and immune-mediated effects may cause bone marrow dysfunction leading to cytopenias. To study the pathological consequences of the T helper response to unresolving chronic

CD4CD25 Regulatory Cells Contribute to the Regulation of Colonic Th2 Granulomatous Pathology Caused by Schistosome Infection [PDF]

, 2011
Eggs of the helminth Schistosoma mansoni accumulate in the colon following infection and generate Th2-biassed inflammatory granulomas which become down- modulated in size as the infection proceeds to chronicity.

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

Advanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.
