How to return to subjectivity? Natorp, Husserl, and Lacan on the limits of reflection

This article discusses the recent call within contemporary phenomenology to return to subjectivity in response to certain limitations of naturalistic explanations of the mind. The meaning and feasibility of this call is elaborated by connecting it to a classical issue within the phenomenological tradition concerning the possibility of investigating the first-person perspective through reflection. We will discuss how this methodological question is respectively treated and reconfigured in the works of Natorp, Husserl, and Lacan. Finally, we will lay out some possible consequences of such a cross-reading for the conception of subjectivity and the concomitant effort to account for this dimension of first-person experience in response and in addition to its omission within the standard third-person perspective of psychological research

Characterization of tumor-directed cellular immune responses in humans

Understanding tumor/host immune interactions may help to fight cancer. Growing knowledge about T cell responses and increasing success of immunotherapeutic approaches have created the need for methods to characterize tumor-directed cellular immune responses. The spectrum of methods reaches from protein-based methods, including tetramers or intracellular flow cytometry, to genetic assays, such as TCR analysis or microarray techniques, further on to functional assays analysing proliferation and microtoxicity. Here, we describe these and further methods and explain their respective application in human tumor immunology

Targets for active immunotherapy against pediatric solid tumors.

Item does not contain fulltextThe potential role of antibodies and T lymphocytes in the eradication of cancer has been demonstrated in numerous animal models and clinical trials. In the last decennia new strategies have been developed for the use of tumor-specific T cells and antibodies in cancer therapy. Effective anti-tumor immunotherapy requires the identification of suitable target antigens. The expression of tumor-specific antigens has been extensively studied for most types of adult tumors. Pediatric patients should be excellent candidates for immunotherapy since their immune system is more potent and flexible as compared to that of adults. So far, these patients do not benefit enough from the progresses in cancer immunotherapy, and one of the reasons is the paucity of tumor-specific antigens identified on pediatric tumors. In this review we discuss the current status of cancer immunotherapy in children, focusing on the identification of tumor-specific antigens on pediatric solid tumors
