Los Angeles Memorial Sports Arena The 160-acre site served as an agricultural fairground from 1872 to 1910. In 1880, John Edward, Ozro W. Childs, former California Governor John G. Downey persuaded the State of California to purchase 160 acres in Los Angeles to foster agriculture in the Southland. Farmers sold their harvest and arces on the grounds, while horses and camels competed on a racetrack where a rose garden now sits and blooms. In 1909, a group of civic-minded individuals led by former Pasadena Mayor Horace Dobbins set about reforming the park, removing the racetrack and other activities and replacing them with gardens and museums. At the 2028 Summer Olympics, the Coliseum will host Athletics as well as the main closing ceremony; the Banc of California Stadium will be one of the soccer venues. Along the northern edge of the park, the Metro Expo Line light rail line serves the park with its Expo Park/USC Station.

Jan Žižka

Jan Žižka z Trocnova a Kalicha was a Czech general, a contemporary and follower of Jan Hus, Hussite military leader, also a Radical Hussite who led the Taborites. Žižka is held to be one of the most renowned military leaders by many historians and today he is considered a Czech national hero. He was born in the small village of Trocnov in the Kingdom of Bohemia into an aristocratic family, he was nicknamed "One-eyed Žižka". From his youth, he was attached to the royal court and held the office of Chamberlain to Queen Sofia of Bavaria, he fought in the Battle of Grunwald. He played a prominent role in the civil wars in Bohemia during the reign of Wenceslas IV. Žižka's tactics were innovative. In addition to training and equipping his army according to their abilities, he used armored wagons fitted with small cannons and muskets, anticipating the tank of five hundred years later, he knew how to exploit geographic features to the full, maintain discipline in his armies. In the Battle of Kutná Hora he defeated the army of the Holy Roman Hungary.

The effectiveness of field artillery against the royal cavalry in the battle turned field artillery into a firm part of Hussite armies. Žižka is considered to be among the greatest military innovators of all time. His accomplishments in this regard are unique and noteworthy as he had to train peasants to face trained and armored opponents who severely outnumbered his own troops, for this, some have considered him to be the greatest general in history. A monument was erected on the Vítkov Hill in Prague to honor Jan Žižka and his victory on this hill in 1420, it is the third largest bronze equestrian statue in the world. Žižka was on the winning side of the Battle of Grunwald called the 1st Battle of Tannenberg, one of the largest battles in Medieval Europe. It was fought on July 1410, during the Polish -- Lithuanian -- Teutonic War; the alliance of the Kingdom of Poland and the Grand Duchy of Lithuania, led by King of Poland Władysław Jagiełło and Grand Duke Vytautas, decisively defeated the Teutonic Knights, led by Grand Master Ulrich von Jungingen.

Most of the Teutonic Knights' leadership were taken prisoner. The Knights never recovered their former power and the financial burden of war reparations caused internal conflicts and an economic downturn in their lands; the battle shifted the balance of power in Eastern Europe. Žižka was the military leader of the Hussites in the Hussite Wars. The Hussites were a proto-Protestant, Christian movement following the teachings of Czech priest, philosopher and master at Charles University in Prague, Jan Hus. On November 13, 1419 a temporary armistice was concluded between the partisans of King Sigismund, the last Emperor of the House of Luxemburg and the citizens of Prague. Žižka disapproved of this compromise and left Prague for Plzeň, one of the richest cities of the kingdom with his followers, but soon left that city. On March 25, 1420 he defeated the partisans of Sigismund at Sudoměř, the first pitched battle of the Hussite wars, he arrived at Tábor, the then-recently established stronghold of the Hussite movement.

The ecclesiastical organization of Tabor had a somewhat puritanical character with a strict military discipline being instituted though the government was established on a democratic basis. Žižka took a large part in the organization of the new military community and became one of the four captains of the people who were at its head. Žižka helped develop tactics of using wagon forts, called vozová hradba in Czech or Wagenburg by the Germans, as mobile fortifications. When the Hussite army faced a numerically superior opponent they prepared carts for the battle by forming them into squares or circles; the carts were joined wheel to wheel by chains and positioned aslant, with their corners attached to each other, so that horses could be harnessed to them if necessary. In front of this wall of carts a ditch was dug by camp followers; the crew of each cart consisted of 16–22 soldiers: 4–8 crossbowmen, 2 handgunners, 6–8 soldiers equipped with pikes or flails, 2 shield carriers and 2 drivers. The Hussites' battle consisted of two stages, the first defensive, the second an offensive counterattack.

In the first stage the army placed the carts near the enemy army and by means of artillery fire provoked the enemy into battle. The artillery would inflict heavy casualties at close range. In order to avoid more losses, the enemy knights attacked; the infantry hidden behind the carts used firearms and crossbows to ward off the attack, weakening the enemy. The shooters aimed first at the horses. Many of the knights died as they fell; as soon as the enemy's morale was lowered, the second stage, an offensive counterattack, began. The infantry and the cavalry burst out from behind the carts striking violently at the enemy from the flanks. While fighting on the flanks and being shelled from the carts the enemy was not able to put up much resistance, they were forced to withdraw, leaving behind dismounted knights in heavy armor who were unable to escape the battlefield. The enemy armies suffered heavy losses and the Hussites soon had the reputation of not taking captives; the Hussite wars marked the earliest successful use of pistols on the battlefield and Žižka was an innovator in the use of gunpowder.

C-C chemokine receptor type 4 is a protein that in humans is encoded by the CCR4 gene. CCR4 has recently been designated CD194; the protein encoded by this gene belongs to the G protein-coupled receptor family. It is a receptor for the following CC chemokines: CCL2 CCL4 CCL5 CCL17 CCL22 Chemokines are a group of small structurally related proteins that regulate cell trafficking of various types of leukocytes; the chemokines play fundamental roles in the development and function of the immune system, they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis. CCR4 is expressed on leukemic cells in cutaneous T-cell lymphoma. Mogamulizumab is a humanised monoclonal antibody targeted at CCR4 and is an investigational drug for CTCL.
