Novel signal transduction pathway utilized by extracellular HSP70: role of toll-like receptor (TLR) 2 and TLR4

A Asea, M Rehli, E Kabingu, JA Boch, O Baré… - Journal of Biological …, 2002 - ASBMB
Recent studies have initiated a paradigm shift in the understanding of the function of heat
shock proteins (HSP). It is now clear that HSP can and do exit mammalian cells, interact with …

Endocytosed HSP60s use toll-like receptor 2 (TLR2) and TLR4 to activate the toll/interleukin-1 receptor signaling pathway in innate immune cells

RM Vabulas, P Ahmad-Nejad, C da Costa… - Journal of Biological …, 2001 - ASBMB
Heat shock proteins (HSPs) require no adjuvant to confer immunogenicity to bound
peptides, as if they possessed an intrinsic" danger" signature. To understand the …

Heat shock protein 70 down-regulates the production of toll-like receptor-induced pro-inflammatory cytokines by a heat shock factor-1/constitutive heat shock element …

E Ferat-Osorio, A Sánchez-Anaya… - Journal of …, 2014 - Springer
Abstract Background Heat shock protein 70 (Hsp70) is an intracellular chaperone protein
with regulatory and cytoprotective functions. Hsp70 can also be found in the extracellular …

HSP70 as endogenous stimulus of the Toll/interleukin-1 receptor signal pathway

RM Vabulas, P Ahmad-Nejad, S Ghose… - Journal of Biological …, 2002 - ASBMB
Human heat-shock protein (HSP) 70 activates innate immune cells and hence requires no
additional adjuvants to render bound peptides immunogenic. Here we tested the …

Heat shock proteins and toll-like receptors

A Asea - Toll-like receptors (TLRs) and innate immunity, 2008 - Springer
Researchers have only just begun to elucidate the relationship between heat shock proteins
(HSP) and Toll-like receptors (TLR). HSP were originally described as an intracellular …

Cutting edge: heat shock protein 60 is a putative endogenous ligand of the toll-like receptor-4 complex

K Ohashi, V Burkart, S Flohé, H Kolb - The Journal of Immunology, 2000 - journals.aai.org
Human heat shock protein 60 (hsp60) elicits a potent proinflammatory response in cells of
the innate immune system and therefore has been proposed as a danger signal of stressed …

T cells respond to heat shock protein 60 via TLR2: activation of adhesion and inhibition of chemokine receptors

A Zanin-Zhorov, G Nussbaum, S Franitza… - The FASEB …, 2003 - Wiley Online Library
Soluble 60 kDa heat shock protein (HSP60) activates macrophages via TLR4. We now
