Pentelute Pfizer-Laubach Career Development Professor of Chemistry Abstract The immune system distinguishes self from non-self to combat pathogenic incursions. Evasion tactics deployed by viruses, microbes, or malignant cells may impede an adequate response. In such cases, therapeutic interventions aid in the elimination of pathogens and the restoration of physiological homeostasis. A major road block in the development of such therapies is the reliance on imperfect detection methods to identify site(s) of infection, or to monitor immune cell recruitment to sites of infection or inflammation in vivo. -
Cell Biology from an Immune Perspective in This Lecture We Will
Harvard-MIT Division of Health Sciences and Technology HST.176: Cellular and Molecular Immunology Course Director: Dr. Shiv Pillai Cell Biology from an Immune Perspective In this lecture we will very briefly review some aspects of cell biology which are required as background knowledge in order to understand how the immune system works. These will include: 1. A brief overview of protein trafficking 2. Signal transduction 3. The cell cycle Some of these issues will be treated in greater depth in later lectures. Protein Trafficking/The Secretory Pathway: From an immune perspective the secretory compartment and structures enclosed by vesicles are “seen” in different ways from proteins that reside in the cytosol or the nucleus. We will briefly review the secretory and endocytic pathways and discuss the biogenesis of membrane proteins. Some of the issues that will be discussed are summarized in Figures 1-3. Early endosomes Late endosomes Lysosomes Golgi Vesiculo-Tubular Compartment ER Figure 1. An overview of the secretory pathway Early endosomes Late endosomes Multivesicular and multilamellar bodies Golgi ER Proteasomes Figure 2. Protein degradation occurs mainly in lysosomes and proteasomes Proteins that enter the cell from the environment are primarily degraded in lysosomes. Most cytosolic and nuclear proteins are degraded in organelles called proteasomes. Intriguingly these two sites of degradation are each functionally linked to distinct antigen presentation pathways, different kinds of MHC molecules and the activation of different categories of T cells. Integral membrane proteins maybe inserted into the membrane in a number of ways, the two most common of these ways being considered in Figure 3. -

Attempts to isolate rare antigen- specific memory B cells for in-depth functional analysis at the single-cell level have Correspondence been hindered by the lack of tools with adequate sensitivity. -
