The radio hosts were talking to a Mommy Blogger (apologies for not recalling her name). What amazed me was a statistic that was given indicatin
Dendritic cell and lymphocyte, coloured scanning electron micrograph (SEM). Interaction between a dendritic cell (blue) and a T lymphocyte (yellow), two components of the body's immune system. Both are types of white blood cell. T lymphocytes recognise a specific site on the surface of pathogens or foreign objects (antigens), bind to it, and produce antibodies or cells to eliminate that antigen. Dendritic cells are antigen- presenting cells (APCs), they present antigens to T lymphocytes…
The acantharians are one of the four types of large amoebae that occur in marine open waters. "Large" in this case is relative, as this microscopic creature have skeletons made of a single crystal of strontium sulfate that quickly dissolves in the ocean water after the cell dies. Together with other microscopic organisms, though, amoebas like this account for most of the biomass on Earth.
T-cell under attack by HIVs. T-cells are part of the immune system, and perform functions such as the detection and destruction of cancerous cells. HIV causes AIDS by de-activating the body’s immune system – one cell at a time. HIVs are shown in blue below.
Hospital-associated Methicillin-resistant Staphylococcus aureus (MRSA) Bacteria. Interaction of MRSA (green bacteria) with a human white cell. The bacteria shown is strain MRSA252, a leading cause of hospital-associated infections in the United States and United Kingdom.
