Our understanding of type 2 immunity has undergone a substantial transformation in recent years, revealing previously unknown functions. Beyond its canonical role in defence against parasitic helminth infections, type 2 immunity safeguards the host through additional mechanisms, including the suppression of excessive type 1 immune responses, regulation of tissue repair and maintenance of adipose tissue homeostasis. However, unlike type 1 immune responses, type 2 immunity is perceived as a potential promoter of tumorigenesis. Emerging evidence challenges this perspective, painting a more nuanced picture in which type 2 immunity might protect against or even actively suppress tumour growth and progression. In this Review, we explore discoveries that highlight the potential of type 2 immunity in reshaping the landscape of cancer immunotherapies.

Background: Lyn kinase, a member of the Src family of tyrosine kinases, predominantly phosphorylates ITIM and ITAM motifs linked to immune receptors and adaptor proteins, and is emerging as a target for Alzheimer's disease (AD). The role of Lyn in TREM2-mediated microglial activation and phagocytosis, a critical pathway for clearing Aβ plaques, remains unclear and potent, selective, and brain penetrant Lyn inhibitors are unavailable. In this study, we report the characterization of Lyn kinase inhibitors from the literature as well as the establishment of an advanced virtual screening platform at the IUSM-Purdue-TREAT-AD center to identify new type II Lyn inhibitors suitable as molecular probes.

Cumulative evidence has indicated a potential reduction in cognitive decline in people with AD, while real-world evidence has shown decreased dementia risk in patients with type 2 diabetes. Non-clinical data reveal that GLP-1RAs impact neuroinflammation and other biological processes believed to be involved in AD pathophysiology, including effects on central and peripheral immune cells.

Background: Chronic stress promotes life-long risk for neuropsychiatric decline by increasing neuroinflammation and disrupting synaptic health and plasticity. Our lab and others have recently demonstrated that non-invasive gamma sensory stimulation (flicker) modulates immune signaling, restores microglial function, and improves cognitive performance in mouse models of Alzheimer's disease (AD). However, no research to date has studied the effects of flicker in the context of stress.

Inositol polyphosphate-5-phosphatase E (INPP5E) is a 5-phosphatase critically involved in diverse physiological processes, including embryonic development, neurological function, immune regulation, hemopoietic cell dynamics, and macrophage proliferation, differentiation, and phagocytosis. Mutations in cause Joubert and Meckel-Gruber syndromes in humans; these are characterized by brain malformations, microphthalmia, situs inversus, skeletal abnormalities, and polydactyly. Recent studies have demonstrated the key role of INPP5E in governing intracellular processes like endocytosis, exocytosis, vesicular trafficking, and membrane dynamics.

Glioblastoma multiforme (GBM) is the most lethal type of primary brain tumor, necessitating the discovery of reliable serum prognostic biomarkers. This study aimed to investigate the prognostic value of serum Interleukin-6 (IL-6) in GBM patients. Bioinformatics analysis via gene set enrichment analysis was conducted on The Cancer Genome Atlas RNA-seq data to explore the pathways enriched in samples with high expression.
