Allergens in trachea. Coloured scanning electron micrograph (SEM) of the surface of the trachea (windpipe) with a number of pollen grains (yellow) attached

Household dust, SEM

Pollen grains, artwork
Pollen grains. Artwork of pollen grains from different flowers. The outer wall (exine) of each pollen grain is highly sculpted to aid their dispersal

Asthma. Computer artwork of allergens (blue and green) amongst alveoli (tiny air sacs, beige) in a lung. Allergens, such as dust and pollen, can trigger an asthma attack

Household dust taken from a vacuum cleaner. Such dust comprises skin cells, dust mites, hairs, soil and earth, pollen grains, fungal spores and food particles

Allergy test
MODEL RELEASED. Allergy test

Histamine allergic reaction, diagram
Histamine allergic reaction. Diagram showing the process that leads to the release of histamine during an allergic reaction. Cells called mast cells (orange) mediate this response

Allergic response, artwork
Allergic response. Computer artwork showing the process that produces an allergic reaction. Antigens (blue), such as pollen

Pollen and dust, artwork
Pollen and dust, computer artwork. Both pollen and dust are allergens that can cause allergic rhinitis when inhaled. Allergic rhinitis is the inflammation of the lining of the nasal cavity

Hay fever, conceptual artwork. Head of a human figure with flower images representing the allergic reaction known as hay fever

Trachea with pollen grains, SEM
Trachea (windpipe) with pollen grains, coloured scanning electron micrograph (SEM). When airborne particles such as pollen grains are breathed in through the nose or mouth

"Allergens: Unseen Culprits That Trigger Our Immune System" Did you know that even the tiniest creatures can cause big trouble for our health? Take a closer look through a scanning electron microscope (SEM), and you'll discover the world lurking around us. Ever heard of eyelash mite tails? Yes, those microscopic critters living on our lashes have tails. These minuscule pests may seem harmless, but their presence can lead to itchy eyes and allergic reactions. But wait, there's more. Honey bees (Apis mellifera) play a vital role in pollination, yet their honey is not always sweet news for everyone. Some individuals are highly allergic to bee stings or even honey itself – an unfortunate consequence of these industrious insects' work. If you think allergens only affect your respiratory system, think again. Trachea-dwelling they are trigger coughing fits and breathing difficulties as they irritate this crucial airway passage. Now let's zoom in on dust mites - tiny arachnids invisible to the naked eye but ever-present in our homes. SEM images reveal their grotesque appearance up close, reminding us why they are such potent allergy triggers. Don't be fooled by their size; these little creatures pack quite a punch. Speaking of household dust, SEM shows us its true composition – a mix of skin flakes, pet dander, pollen grains from outside visitors like plants and trees – all potential sources of allergies within our own four walls. Ah yes, pollen grains - beautiful artwork under the microscope lens but capable of causing sneezing fits and watery eyes for many during allergy season. Nature's way of spreading life becomes an annoyance for some unlucky souls. Whether it's eyelash mite tails tickling your lids or dust mites making themselves at home in your mattress fibers - allergens surround us.
