Autophagy Scientific Review

Written by Patricia Boya and Patrice Codogno, this review summarizes the molecular mechanisms, physiology and pathology of autophagy. The role of autophagy in cell death and its links to disease are also discussed. Compounds available from Tocris are listed.

MAPK Signaling

MAPK Signaling Scientific Review

MAP kinase signaling is integral to the regulation of numerous cellular processes such as proliferation and differentiation, and as a result is an important focus of cancer and immunology research. Updated for 2016, this review discusses the regulation of the MAPK pathway and properties of MAPK cascades. Compounds available from Tocris are listed.


Alzheimer's Poster

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.


Autophagy Poster

Autophagy is a cellular process used by cells for degradation and recycling. Written by Patricia Boya and Patrice Codogno, this poster summarizes the molecular machinery, physiology and pathology of autophagy. Compounds available from Tocris are listed.


Parkinson's Poster

Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
