Walter R. Terra has B.sc in biology (1968) and a Ph.D. (1972) in biochemistry from the University of Sao Paulo and since 1990 he is Professor of Biochemistry at the Department of Biochemistry from the Institute of Chemistry of the University of Sao Paulo. He is a member of the Brazilian Academy of Sciences and the recipient of the National Medal of the Scientific Merit. He was head of the Biochemistry Department (1996-2000; 2004-2006), vice-director of the Institute of Chemistry (2006-2010) of the same University and General Secretary of the Brazilian Society of Biochemistry and Molecular Biology, since 1992. Professor Terra is member of the editorial board of the leading journals of his area of expertise (Insect Biochemistry and Molecular Biology; Insect Molecular Biology) and was ad hoc adviser of most funding agencies in Brazil and some from abroad like NIH (USA). His papers deal with the molecular physiology of insect digestion, including the 3D analysis of chosen midgut proteins and evolutionary considerations. He has published about 160 papers that were cited more than 4136 times, according to ISI-Thompson. (Source: Lattes Curriculum)

The objective of this project is to describe the spatial organization of the midgut physiological processes and their underlying molecular events of insect types pertaining to different orders. The aim of these studies is to find out general principles from which hypotheses can be advanced in relation to the digestive and absorptive processes and tissue metabolic interactions of insects n…
A project for a visiting researcher for one year at the University of São Paulo, Invited research: Dr. Carlos Peres SilvaProject: Digestion and midgut absorption in 3 insects. An enzymological, transriptomic and proteomic approach.This project is part of the Projeto Tematico FAPESP (Process: 2017/08103-4), coordinated by Dr. Walter R. Terra, which intends to describe the molecular process…
The cockroach Periplaneta americana is a very abundant insect in our country and has a great plasticity in the digestion of a wide variety of compounds, including plant lignocellulose compounds (mainly composed of cellulose, hemicellulose and lignin) . The aim of project is to study the cellular and biochemical influence of diet on digestion of lignocellulosic compounds in the cockroach P…

Although there is much work on sugar transporters (Bifano et al., 2010; Price and Gatehouse, 2014), amino acids (Evans et al., 2009; Boudko, 2012), peptides (Roman et al., 1998), lipids (Dourlen et al., 2015), as well as ions (Chintapalli et al., 2015; Xiang et al., 2012) in insects, a comprehensive molecular analysis of intestinal physiology using transporters is at an early stage. A wor…
Different groups of insects diverged along the evolutionary history in the characteristics of their digestive systems. Over the past 30 years, our group has looked to understand these peculiarities in different insect orders. In this context, some of our results include differences in overall morphology, composition, synthesis and secretion rates of digestive enzymes, variations in the in…
Rhodnius prolixus blood meal ingestion activates a cascade of hormonally coordinated events involving different tissues to eliminate excess water and sodium chloride from the blood. This postprandial diuresis stimulates defecation/urination, thus reducing its body weight, preventing them from predation, and allowing blood digestion. When R. prolixus is infected, the parasite Trypanosoma c…
Insecta is one of the most diverse and widely distributed groups of organisms in the world. This diversification is largely a result of insects' ability to explore a wide range of sources of energy, which is coupled to highly specialized digestive systems. Insect taxonomic groups differ on their gut morphophysiological characteristics, such as in their enzymatic and molecular transporters…
