Tuberculosis bacteria find shelter from drugs and the body’s defenses in bone marrow stem cells.

By revealing that animals could develop immune responses against their own tissues, the physician-scientist established an entirely new field of science.

This month marks the 100-year anniversary of BCG, still the only approved vaccine against the lethal pathogen. But there are new vaccines for this wily foe on the horizon.

Human natural killer cells, previously considered not to participate in adaptive immunity, remember viral antigens after initial exposures, according to a new study.

Through their effects on metabolism and immunity, bacteria in the gut affect whether medications will be effective for a given patient.

Lyme disease–causing bacteria can outmaneuver antibiotics in vitro and manipulate the mouse immune system.

Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement.

Sorting out T-cell functional and phenotypic heterogeneity depends on studying single cells.

Updated classics and new techniques help microbiologists get up close and quantitative.

Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod
