Our major goal is to understand those changes in lipid composition, fluidity- and microdomain organization of plasma and endo-membranes which alter the expression of the stress protein molecular chaperones (HSPs). Among the specific transcription factors, HSF1 plays a central role in this “membrane-controlled” boosting or silencing of HSPs. The relationship between the specific distribution of lipid rafts and the concomitant changes in the level, profile and cellular distribution of HSPs is currently determined via monitoring the surface membrane microdomains with confocal- and ultrasensitive single molecular microscopy. Through comparative lipidomics, key lipid molecular species involved in the activation or attenuation of HSP signaling pathways are identified. We have shown that membrane-associated HSPs can control major attributes of the membranes, like fluidity, permeability, curvature, and the operation of raft-associated signaling platforms. Moreover, membrane association of HSPs can refine hsp gene expression. Applying these principles can yield novel pharmaceutical agents that have the potential of major therapeutic benefit to a number of diverse disease states.

Stress protein molecular chaperones

Induced by a wide range of stressors, from temperature stress to hypoxia, inflammation, infections or environmental pollutants, stress proteins, also termed heat shock proteins (HSPs) play key roles in living systems. The HSPs are named according to their molecular weights. HSP100, HSP90, HSP70, HSP60 and the “small heat shock proteins”, each define families of chaperones.

The HSP molecular chaperones are able to recognize damaged proteins and to redirect them to repair (refolding) or to proteolysis. By helping to stabilize partially unfolded proteins, HSPs aid in transporting proteins across membranes within the cell. HSPs can regulate the life or death of cells by directly modulating certain apoptotic signaling events or indirectly, by participating in antigen processing.

Stress proteins in the membranes

Quite surprisingly, a subpopulation of HSPs is present either on the surface or within the cellular membranes. As we have shown in our studies described below, via their specific lipid and protein interactions certain HSPs can control major attributes of membranes. The membrane (raft or non-raft) associated HSPs can also participate in the orchestration of distinct stress signaling platforms. In spite of lacking a secretory signal, some HSPs are mysteriously released from cells by various secretory mechanisms. Irrespective of the secretory routes chosen (raft-, exosome- or secretary granule-mediated, etc.), these exogenous HSPs can then stimulate both the innate and the adaptive immune system.

Stress response from membranes and back to membranes: lessons from unicellular stress models

An earlier “central dogma” suggested that stress-induced protein denaturation serves as a sole primary stress-sensing machinery, which triggers Hsp gene expression. From the past decade, we have introduced and experimentally verified a new but not exclusive cellular “thermosensor” model, which predicts the existence of membrane-associated stress sensing and signaling mechanisms. As depicted below (see Fig.1.), we propose that changes in the physical state (fluidity) and/or composition of lipid molecular species with the concomitant destabilization/reorganization of membrane microdomains may serve as the “primary molecular switch” for the operation of these “cellular thermometers”.

The striking similarities of the human and Schizosaccharomyces pombe (fission yeast) signal transduction pathways prompted us to introduce S. pombe as a powerful and complementary “micromammal” model. We use it for elucidating early activation steps of the heat shock response including membrane-associated stress sensors, stress signaling pathways and the interplay of potential cellular stress survival strategies (i.e. the concerted and complementary actions of sugar (trehalose), protein (HSP), and lipid chaperones). Thus, the S. pombe model may allow studying the individual members or the entire stress-protective network in a simple cellular context.

Figure 1. A model of the crosstalk between the stress sensory membrane, hsp gene expression, and the membrane association of a specific subset of HSPs (see Vigh et al, TIBS, 2007). Temperature stress modifies the physical state of the membrane and this activates a membrane signal culminating in the transcription of hsp genes. In turn, as our group evidenced for various prokaryotic models, specific subsets of HSPs (e.g. GroESL and the small HSP called HSP17 in the blue-green alga Synechocystis) localize with specific membrane domains temporarily via newly formed “heat shock lipids”, thus re-establishing proper membrane lipid order and phase-state that then may turn off hsp gene transcription.

Membrane-regulated stress response in mammalian cells: lipid rafts at the crossroad

Due to their multiple and vital functions, stress proteins play a fundamental role in the pathology of several human diseases. Aberrantly high levels of certain HSP classes are characteristic in cancer cells and the converse situation applies for type-2 diabetes or neurodegeneration. In accordance, understanding the mechanism whereby mammalian cells can elicit a stress protein response is of key importance. In addition, correcting the defects of membrane domains, engaged in the generation and transmission of stress signals may be of paramount importance for the design of new drugs with the ability to induce or attenuate the level of a particular class of heat shock proteins (see Fig.2.).

Figure 2. Membrane-mediated stress protein response and the cellular localization of HSPs (highlighted by HSP70) in mammalian cells (see Horváth et al., BBA, 2008). HSF1 is a key coordinator of the initiation of heat shock gene transcription, which is activated mainly by the appearance of denatured or misfolded proteins. In addition, stress sensing-signaling mechanisms operate through stress-induced membrane rearrangements. Such typical membrane-mediated changes that are evidenced to refine the expression of heat shock genes are the non-specific clustering of the growth factor receptors associated with membrane microdomains (“rafts”) (1) or the activation of phospholipases (2), which sequester themselves into unsaturated-rich microdomains and cleave arachidonic acid, a known HSP inducer. Stress activation of such pathways alters the nuclear accumulation and transactivation capacity of HSF1 (3) via its covalent post-translational modifications and ultimately retailor the abundance and profile of HSPs. The function of individual HSPs (highlighted on the scheme by HSP70) depends on their intracellular, membrane bound or extracellular location. The major action of chaperone proteins in the cytosol is to maintain protein homeostasis (4). HSP70 can promote cell survival by inhibiting lysosomal membrane permeabilization via the interaction with specific lipids (5). We are currently studying the interaction of HSPs with cellular lipid droplets. Experimental evidence is accumulating in favor of the presence of HSP70 (and other HSPs) in lipid rafts as components of signaling or trafficking platforms (6). HSPs can also associate with specific lipids and proteins in the plasma membrane, inducing “membrane stabilization” and/or exhibiting an immunogenic potential (7). HSP70s of extracellular location (8) have immunomodulatory capacities and are potent agents in the activation of the innate and adaptive immune system.

Lipidomics of stress response – Lipids in health and disease

Lipids are central to the regulation and control of cellular processes by acting as basic building units for biomembranes, the platforms for the vast majority of cellular functions. Recent developments in lipid mass spectrometry have set the scene for better understanding the composition of membranes, cells and tissues by allowing the precise identification and quantification of the altered levels of lipids induced by a disease state, a gene mutation (knockout, or over-expression), a therapeutic treatment, or other perturbations.
