Human monoclonal antibodies show promise as treatment and prevention for influenza B

by

Researchers at Vanderbilt University Medical Center (VUMC) have made a significant breakthrough by isolating human monoclonal antibodies against influenza B. This virus is a notable public health threat, particularly affecting children, the elderly, and individuals with weakened immune systems. While seasonal flu vaccines provide coverage against both influenza A and B, they do not always … Read more

Animal Development: Embryonic Development and Morphogenesis

by

Animal development, also known as embryonic development, encompasses the complex processes through which a single fertilized egg cell transforms into a multicellular organism with distinct tissues, organs, and body structures. This intricate journey involves cellular differentiation, tissue organization, morphogenetic movements, and regulatory mechanisms that orchestrate the formation of body axes, germ layers, organ systems, and … Read more

Developmental Biology: Processes from Fertilization to Organism Formation

by

Developmental biology is a fascinating field that explores the processes governing the growth, differentiation, and organization of cells into complex multicellular organisms. From the moment of fertilization, when a sperm cell fuses with an egg cell, to the formation of fully functional organs and tissues, developmental biology seeks to unravel the intricate molecular, cellular, and … Read more

Animal Physiology: Functions and Adaptations in Animals

by

Animal physiology is the branch of biology that focuses on understanding the biological functions and adaptations of animals, ranging from microscopic organisms to complex multicellular organisms. It encompasses a wide range of topics, including cellular processes, organ systems, homeostasis, metabolism, reproduction, behavior, and adaptations to diverse environments. By studying animal physiology, scientists gain insights into … Read more

Study reveals host cell immunity plays key Role in bacteriophage therapy

by

A groundbreaking collaboration between micro- and immunobiologists from prestigious institutions like Dartmouth Geisel School of Medicine, Yale University, and the University of Pittsburgh has unveiled a crucial aspect overlooked in bacteriophage therapy research. Their findings, published in PLOS Biology, challenge the conventional approach and underscore the need to integrate host cell response into future studies on … Read more

Researchers develop new method to study cellular interactions in living organisms

by

Researchers at Princeton and Rockefeller University have found a new way to study cellular communication, recording interactions between cells as they work in a living organism and unlocking new ways to understand how our bodies function. Cell interactions are essential to fighting disease and forming tissue, said Yuri Pritykin, assistant professor of computer science, the … Read more

New adhesion GPCR “mayo” influences gut and heart function in fruit flies, may be relevant in humans

by

Adhesion GPCRs are a group of G protein-coupled receptors associated with many bodily functions and diseases in humans. Scientists at Leipzig University have discovered a new receptor—which they have named “mayo”—and found that it influences the development of the small intestine and heart function in fruit flies, and that these phenomena may also be relevant … Read more

Study links persistent UTI pain to nerve cell overgrowth in bladder

by

A perplexing problem for people with recurring urinary tract infections (UTIs) is persistent pain, even after antibiotics have successfully cleared the bacteria. Now Duke Health researchers have identified the likely cause—an overgrowth of nerve cells in the bladder. The finding, appearing March 1 in the journal Science Immunology, provides a potential new approach to managing … Read more
