Enhancing immunity during ageing by targeting interactions within the tissue environment tinyurl.com/2m84cfjy This new Review discusses how inflammation and senescence drive each other during aging, leading to loss of immune function, and discusses approaches to address this

Excited to share our latest review in @NatRevDrugDisc!🚨 tinyurl.com/2m84cfjy Studies to boost immunity during ageing consider effects of potential therapies on cell types. Here, we highlight how inflammation & senescence drive each other leading to loss of immune function.👇🏼

We discuss the relative merits and drawbacks of therapies that are directed at eliminating senescent cells (senolytics) and those that inhibit inflammation (senomorphics) in the context of tissue niches.

We also discuss strategies designed to directly boost immune cell function and those that improve immune surveillance in tissues.

Our newest paper is out! 🚨 We have uncovered multiple cellular senescence-associated defects in melanocytes and other cell types in Familial Melanoma Syndrome (FMS) patients with a p16 defect that makes them more susceptible to developing melanoma ⬇️ onlinelibrary.wiley.com/doi/…

Multiple outcomes of the germline p16INK4a mutation affecting senescence and immunity in human skin

(a) In the skin fibroblasts are a key source of SASP production, with melanocytes having significantly less production. In healthy individuals, senescent fibroblasts play a major role in attracting...

CD4+ and CD8+ T cell numbers were reduced in FMS patient skin. Patient-derived fibroblasts were also found to secrete less SASP which may hinder the recruitment of T cells in steady state and thus reduce cutaneous immunosurveillance.

This is the 1st in-depth characterisation of multiple senescence-associated outcomes in different cells types as a result of a p16 gene mutation in FMS. This will ultimately be highly relevant for better understanding the role of senescent cells in regulating immunity in tissues.

Out now🚨 #VitaminD blocks the SASP and p38 MAPK in senescent fibroblasts to improve cutaneous immune responses during #ageing. In this study by our postdoc @sourayasayegh &co, we explored how vitamin D boosts immunity @Aging_Cell👇🏼 doi.org/10.1111/acel.14093 @Emma_S_Chambers

Vitamin D3 inhibits p38 MAPK and senescence‐associated inflammatory mediator secretion by senescent...

Ageing is associated with decreased cutaneous immunity and increased inflammageing. Senescent dermal fibroblasts increase in the skin and secrete cytokines and chemokines known as the senescence-as...
