are important in cell signaling. Their release has an effect on the
behavior of cells around them. It can be said that cytokines are involved
in autocrine signalling, paracrine signalling and
as immunomodulating agents. Their definite distinction from hormones is
still part of ongoing research. Cytokines include chemokines, interferons,
interleukins, lymphokines, and tumour necrosis factors but generally not
hormones or growth factors (despite some overlap in the terminology).
Cytokines are produced by a broad range of cells, including
like macrophages, B
lymphocytes, T lymphocytes and mast cells, as well as endothelial cells,
fibroblasts, and various stromal cells; a given cytokine may be produced
by more than one type of cell. They act through receptors, and are
especially important in the immune system; cytokines modulate the balance
between humoral and cell-based immune responses, and they regulate the
maturation, growth, and responsiveness of particular cell populations.
Some cytokines enhance or inhibit the action of other cytokines in complex
ways. They are different from

array of virulence factors. Some are chromosomally encoded and intrinsic
to the bacteria (e.g. capsules and endotoxin), whereas others are obtained
from mobile genetic elements like plasmids and bacteriophages (e.g. some
exotoxins). Virulence factors encoded on mobile genetic elements spread
through horizontal gene transfer, and can convert harmless bacteria into
dangerous pathogens. Bacteria like

majority of their virulence from mobile genetic elements. Gram-negative
bacteria secrete a variety of virulence factors at host-pathogen
interface, via membrane vesicle trafficking as bacterial outer membrane

is a viral infectious
disease of the upper respiratory tract that primarily affects the nose.
The throat, sinuses, and voice box may also be affected. Signs and
symptoms may begin less than two days following exposure. They include
coughing, sore throat, runny nose, sneezing, headache, and fever. People
usually recover in seven to ten days. Some symptoms may last up to three
weeks. In those with other health problems, pneumonia may occasionally
Why do people catch colds more in the
One reason is that we spend more time indoors in
the winter, meaning that we’re in closer contact with other
people who may be carrying germs. Viruses from coughs and
can hang around in the air for days because of the drier
air in the winter. Another reason is that the cold weather also
wears down your body’s defenses against infection
. In the short
days of winter, without much sunlight, we may run low on Vitamin
D, which helps power the body’s immune system, making us more
vulnerable to infection. And on top of that when we breathe in
cold air, the blood vessels in our nose may constrict to stop us
losing heat. This may prevent white blood cells (the warriors
that fight germs) from reaching our mucus membranes and killing
any viruses that we inhale, allowing them to slip past our
defenses unnoticed. (It could be for this reason that we tend to
catch a cold if we go outside with wet hair.
is the blockage of the
nasal passages usually due to membranes lining the nose becoming swollen
from inflamed blood vessels.

is the result of alternating
congestion and decongestion of the nasal conchae or turbinates,
predominantly the inferior turbinates, which are by far the largest of the
turbinates in each nasal fossa. The cycle, which is controlled by the
autonomic nervous system
has a mean duration of two and a half hours. It has been shown that the
cilia of the congested side suspend their motility until that side
decongests. Thus the cycle ensures that one side of the nose is always
moist, to facilitate humidification, which is one of the three functions
of the nose, the other two being filtration and warming of inspired air

Phlegm is in essence a water-based gel consisting of glycoproteins,
immunoglobulins, lipids and other substances. Its composition varies
depending on climate, genetics, and state of the immune system. Its color
can vary from transparent to pale or dark yellow and green, from light to
dark brown, and even to dark grey depending on the constituents.

severity and combination of productive or dry cough, chest pain, fever,
and trouble breathing, depending on the underlying cause. Pneumonia is
usually caused by infection with viruses or bacteria and less commonly by
other microorganisms, certain medications and conditions such as
autoimmune diseases. Risk factors include other lung diseases such as
cystic fibrosis, COPD, and asthma, diabetes, heart failure, a history of
smoking, a poor ability to cough such as following a stroke, or a weak
immune system. Diagnosis is often based on the symptoms and physical
examination. Chest X-ray, blood tests, and culture of the sputum may help
confirm the diagnosis. The disease may be classified by where it was
acquired with community, hospital, or health care associated pneumonia.

Symptoms can be mild to severe. The most common symptoms include: a high
fever, runny nose, sore throat, muscle pains, headache, coughing, and
feeling tired. These symptoms typically begin two days after exposure to
the virus and most last less than a week. The cough, however, may last for
more than two weeks. In children, there may be nausea and vomiting, but
these are not common in adults. Nausea and vomiting occur more commonly in

that, being subclinical, is nearly or completely asymptomatic (no signs or

of a microbe, intestinal parasite, or virus that usually is a pathogen
causing illness, at least in some individuals. Many pathogens spread by
being silently carried in this way by some of their host population. Such
infections occur both in humans and nonhuman animals. An example of an
asymptomatic infection is a mild common cold that is not noticed by the
infected individual. Since subclinical infections often occur without
eventual overt sign, their existence is only identified by microbiological
culture or DNA techniques such as polymerase chain reaction.

release has an effect on the behavior of cells around them. It can be said
that cytokines are involved in autocrine signalling, paracrine signalling
and endocrine signalling as immunomodulating agents. Their definite
distinction from hormones is still part of ongoing research. Cytokines
include chemokines, interferons, interleukins, lymphokines, and tumour
necrosis factors but generally not hormones or growth factors (despite
some overlap in the terminology). Cytokines are produced by a broad range
of cells, including immune cells like macrophages, B lymphocytes, T
lymphocytes and mast cells, as well as endothelial cells, fibroblasts, and
various stromal cells; a given cytokine may be produced by more than one
type of cell. They act through receptors, and are especially important in
the immune system; cytokines modulate the balance between humoral and
cell-based immune responses, and they regulate the maturation, growth, and
responsiveness of particular cell populations. Some cytokines enhance or
inhibit the action of other cytokines in complex ways. They are different
from hormones, which are also important cell signaling molecules, in that
hormones circulate in less variable concentrations and hormones tend to be
made by specific kinds of cells. They are important in health and disease,
specifically in host responses to infection, immune responses,
inflammation, trauma, sepsis, cancer, and reproduction.
