Recently, our group demonstrated that viral delivery of wild-type Hsp27 into the brains of tau-transgenic mice reduced tau levels and rescued long-term potentiation deficits. PubMed:21882945
Taken together, pathological hyperphosphorylated tau caused cell death, and Hsp27 attenuated the cell toxicity of pathological hyperphosphorylated tau. PubMed:14963027
Here we show that heat shock protein 27 (Hsp27) preferentially binds pathological hyperphosphorylated tau and paired helical filaments tau directly but not non-phosphorylated tau. The formation of this complex altered the conformation of pathological hyperphosphorylated tau and reduced its concentration by facilitating its degradation and dephosphorylation. PubMed:14963027
The importance of sHSPs in disease was originally noted from the observations that HSPB1 and CRYAB were overexpressed in AD brains (Shinohara et al., 1993; Renkawek et al., 1994a,b) and HSPB1, CRYAB, HSPB6 and HSPB8 were associated with AD plaques (Shao et al., 2012). PubMed:27491084

During protein quality control, Hsp70, Hsp90 and Hsp27 (and their co-chaperones) often work in concert. If prolonged misfolding is detected, the chaperones shuttle the protein to a degradation endpoint, such as the proteasome or autophagy PubMed:21882945

Hsp27 has emerged as a potential target for tau regulation based on early findings that it preferentially binds to phosphorylated and hyperphosphorylated tau and promotes their clearance [125,126] PubMed:21882945

However, astrocyte-derived Hsp27 has been shown to promote tau accumulation and Hsp27 associates with tau tangles in a mouse model [127,128], suggesting a more complex relationship PubMed:21882945
