Article Abstract
Staphylococcus aureus is a formidable pathogen and major challenge to human health. However, the bacterium is dichotomous and also acts as an asymptomatic coloniser. Given its ubiquity, every individual has been exposed to the bacterium, which may 'tune' the host immune system. This prior exposure potentially hampers the efficacy of anti-S. aureus vaccines, diminishing their protective effect. Conversely, by preserving its niche as a commensal coloniser, the bacterium simultaneously contributes to host defence through interbacterial competition and stimulation of host immune responses, potentially fending off pathogenic threats. This review examines how S. aureus shapes host immunity via infection and colonisation and explores how S. aureus-associated immune tuning can be both problematic and beneficial for the host.

Vitamin B12 is a vital water-soluble vitamin containing a central cobalt atom within its corrin ring structure. It exists in several derivatives, among which methylcobalamin (MeCbl) and adenosylcobalamin (AdCbl) are the biologically active forms that serve as cofactors in essential enzymatic reactions. Although the neurological and hematological consequences of vitamin B12 deficiency have been extensively studied, its role in immune regulation remains less well understood.

Zika virus (ZIKV) is a mosquito-borne flavivirus causing a major epidemic in the Americas in 2015. Dendritic cells (DCs) are leukocytes with key antiviral functions, but their role in ZIKV infection remains under investigation. While most studies have focused on the monocyte-derived subtype of DCs, less is known about conventional dendritic cells (cDCs), essential for the orchestration of antiviral adaptive immunity.

Novel immunopotentiators are essential for advancing our understanding of immune receptor crosstalk and for addressing infectious diseases. Previous studies have suggested that coactivation of nucleotide-binding oligomerization domain-containing protein 2 (NOD2) and Toll-like receptor 4 (TLR4) can synergistically enhance the immune response. To investigate this synergy, we synthesized and evaluated a series of conjugated NOD2/TLR4 dual agonists comprising our in-house NOD2 agonist and two structurally distinct TLR4 agonists connected via flexible or rigid linkers.

Here, we report the development and mechanism of ACTIVATE (Adoptive Cell Therapy and Immunostimulatory Vehicle for Anti-Tumor Efficacy), which leverages an injectable hydrogel depot technology that forms a transient inflammatory niche for localized co-delivery of adoptive T cells and native cytokines. By tuning cytokine identity, ACTIVATE enables precise modulation of T-cell expansion, effector function, and interaction with endogenous immune networks.
