Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers
Chemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

CD8+ T cell migration to the skin requires CD4+ help in a murine model of contact hypersensitivity. [PDF]
PLoS ONE, 2012 The relative roles of CD4+ and CD8+ T cells in contact hypersensitivity responses have not been fully solved, and remain an important question. Using an adoptive transfer model, we investigated the role of the respective T cell subset.

The Relationship Between (Endo)cannabinoids, the Microbiome and Melanoma
Pharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.CB1 and CB2 receptors are widely distributed in both normal and cancerous cells. Cannabinoids have a positive impact on reducing tumor growth in mice. A positive relationship exists between CB2 receptors and survival in skin melanoma. However, there is a negative impact on non‐small cell lung cancer and colon cancer, whereas a higher association of CB1

Spectroscopic Evidence for an Oxazolone Structure in Anionic -Type Peptide Fragments [PDF]
, 2011 Infrared spectra of anionic b-type fragments generated by collision induced dissociation (CID) from deprotonated peptides are reported. Spectra of the b2 fragments of deprotonated AlaAlaAla and AlaTyrAla have been recorded over the 800-1800 cm-1 spectral
