Immunity in context: science and society in dialogue

Según el paradigma dominante en inmunología, la inmunidad está basada en la discriminación entre yo/no-yo y requiere, por tanto, una construcción de la identidad. Dos orientaciones compiten por dominar: la concepción original, concebida en el contexto de las enfermedades infecciosas contempla al organismo como aislado y autónomo, como una entidad que necesita defender sus fronteras. Una visión alternativa sitúa firmemente al organismo en su entorno, en el cual suceden tanto encuentros beneficiosos como costosos. En este enfoque relacional, la tolerancia activa permite relaciones cooperativas con otros organismos en una economía ecológica más amplia. Estas orientaciones en liza —una derivada de la biomedicina y otra de las ciencias ecológicas— han llamado la atención de los científicos sociales y de los críticos de la cultura. Por una parte, el feminismo ha descrito la teoría inmunológica como basada en nociones sociales prestadas de identidad que reflejan los valores agresivos del macho y que, de este modo, impiden una explicación más equilibrada de la inmunidad. Por otra parte, otro comentario proyecta la teoría inmunológica como un marco en el que el análisis de las sociedades occidentales revela aparentemente patrones análogos de interacciones ‘yo’ y ‘otros’, en las que la autoinmunidad y la inmunización son entendidas como expresiones de la comprensión insular de la identidad. Se ofrece aquí una meta-representación que muestra cómo estas críticas sitúan al yo inmune en un espectro que va desde su formulación como un agente autónomo, una concepción modernista del individuo independiente, a una visión postmoderna en la que esta concepción de la identidad ha sido deconstruida. De acuerdo con esto, la inmunología recoge un amplio debate sobre la agencia en el que diferentes interpretaciones de la inmunidad sirven como molde en el que se modelan comprensiones competidoras de la comprensión de las relaciones sociales humanas.; Without disputing the richness of the original incarnation of the immune self – conceived in segregated terms and defended by immunity – this useful heuristic is undergoing transformation. A relational or dialectical orientation has supplemented this incarnation of selfhood from an exclusive focus on the defensive scenario to one that now accommodates more expansive ecological intercourse, one in which active tolerance allows for cooperative exchanges within both the internal and external environments. This revision that emphasizes communal relationships finds support in the social matrix. Just as the autonomous immune self found its own conceptual coordinates in modernist notions of personal identity, changing cultural values, revised notions of personal identity, and the vast growth of ecological awareness resonate with shifts in theorizing about immunity. Such correspondence highlights the ready movement of potent metaphors between the laboratory and its supporting culture

The Triumph of Uncertainty

Tauber, a leading figure in history and philosophy of science, offers a unique autobiographical overview of how science as a discipline of thought has been characterized by philosophers and historians over the past century. He frames his account through science’s – and his own personal – quest for explanatory certainty. During the 20th century, that goal was displaced by the probabilistic epistemologies required to characterize complex systems, whether in physics, biology, economics, or the social sciences. This “triumph of uncertainty” is the inevitable outcome of irreducible chance and indeterminate causality. And beyond these epistemological limits, the interpretative faculties of the individual scientist (what Michael Polanyi called the “personal” and the “tacit”) invariably affects how data are understood. Whereas positivism had claimed radical objectivity, post-positivists have identified how a web of non-epistemic values and social forces profoundly influence the production of knowledge. Tauber presents a case study of these claims by showing how immunology has incorporated extra-curricular social elements in its theoretical development and how these in turn have influenced interpretive problems swirling around biological identity, individuality, and cognition. The correspondence between contemporary immunology and cultural notions of selfhood are strong and striking. Just as uncertainty haunts science, so too does it hover over current constructions of personal identity, self knowledge, and moral agency. Across the chasm of uncertainty, science and selfhood speak

Philosophy of immunology

Philosophy of immunology is a subfield of philosophy of biology dealing with ontological and epistemological issues related to the studies of the immune system. While speculative investigations and abstract analyses have always been part of immune theorizing, until recently philosophers have largely ignored immunology. Yet the implications for understanding the philosophical basis of organismal functions framed by immunity offer new perspectives on fundamental questions of biology and medicine. Developed in the context of history of medicine, theoretical biology, and medical anthropology, philosophy of immunology differs from these related branches of study in its focus on traditional philosophical questions concerning identity, individuality, ecology, cognition, scientific methodology and theory construction. This broad agenda derives from immunology’s multifaceted research program that has developed from its initial clinical challenges of host defense, transplantation, autoimmunity, tumor immunology, and allergy. In addition to these well-established research areas, immunity is now understood to play a central role in other physiological functions, development, ecology, and evolutionary mechanics. Holding together these diverse domains of inquiry lie philosophical commitments oriented by organismal identity. In this regard, pertinent issues are raised concerning cognition (organization of immune perception and information processing), the character of individuality (framed by the ecological context of immune-mediated assimilation and rejection), and the dynamics of complex systems (understood as holistic systems biology). Indeed, immunology, in the context of cognitive science, evolutionary biology, environmental sciences, and development provides multi-focal perspectives for philosophy of science

Network Theory Analysis of Antibody-Antigen Reactivity Data: The Immune Trees at Birth and Adulthood

Motivation: New antigen microarray technology enables parallel recording of antibody reactivities with hundreds of antigens. Such data affords system level analysis of the immune system’s organization using methods and approaches from network theory. Here we measured the reactivity of 290 antigens (for both the IgG and IgM isotypes) of 10 healthy mothers and their term newborns. We constructed antigen correlation networks (or immune networks) whose nodes are the antigens and the edges are the antigen-antigen reactivity correlations, and we also computed their corresponding minimum spanning trees (MST) – maximal information reduced sub-graphs. We quantify the network organization (topology) in terms of the network theory divergence rate measure and rank the antigen importance in the full antigen correlation networks by the eigen-value centrality measure. This analysis makes possible the characterization and comparison of the IgG and IgM immune networks at birth (newborns) and adulthood (mothers) in terms of topology and node importance. Results: Comparison of the immune network topology at birth and adulthood revealed partial conservation of the IgG immune network topology, and significant reorganization of the IgM immune networks. Inspection of the antigen importance revealed some dominant (in terms of high centrality) antigens in the IgG and IgM networks at birth, which retain their importance at adulthood

Disclosure and rationality: Comparative risk information and decision-making about prevention

With the growing focus on prevention in medicine, studies of how to describe risk have become increasing important. Recently, some researchers have argued against giving patients "comparative risk information," such as data about whether their baseline risk of developing a particular disease is above or below average. The concern is that giving patients this information will interfere with their consideration of more relevant data, such as the specific chance of getting the disease (the "personal risk"), the risk reduction the treatment provides, and any possible side effects. I explore this view and the theories of rationality that ground it, and I argue instead that comparative risk information can play a positive role in decision-making. The criticism of disclosing this sort of information to patients, I conclude, rests on a mistakenly narrow account of the goals of prevention and the nature of rational choice in medicine
